New Blighted Ovum Guidelines! Chances Are You Are Being Diagnosed Too Soon!

  • Author:
  • Updated date:

My name is Kay. As a result of my two misdiagnosed miscarriages, I've done a lot of research about pregnancy and its complications.

Are you being diagnosed with a blighted ovum too soon?

Are you being diagnosed with a blighted ovum too soon?

Before You Agree to End Your Pregnancy, You Really Need to Know This!

I am often asked questions about the diagnosis of a blighted ovum because of my own misdiagnosed blighted ovum story.

Whether you are going through a blighted ovum scare of your own, or know somebody who is, I want to encourage you to save this page and share it! This may save a life!

The UK has implemented new guidelines that, as a result, will save many babies. The United States and most other countries are still woefully behind and using antiquated standards that cause many women to be misdiagnosed. Even if you are from the UK, not all doctors are up to date. I encourage you to take these new standards with you to your next doctor's appointment.

You are your own best advocate!

I am not a medical professional. The information I share here is not meant to replace the information given to you by your doctor. If you feel your doctor is not doing enough for you or is not willing to listen to your concerns, I strongly encourage you to get a second opinion.

What Is a Blighted Ovum?

A blighted ovum occurs when a fertilized egg implants in the uterus but doesn't develop into an embryo (WebMD).

Simply, it just means the baby doesn't develop past implantation or is so early that you wouldn't see evidence of it via ultrasound.

I hear from women who they've been diagnosed with a blighted ovum because the doctor only sees a yolk sac in the gestational sac. This is not a blighted ovum!

If there is a yolk sac, there is strong evidence there is a baby. In the Journal of Ultrasound in Medicine, the article "Sonographic Evaluation of the Yolk Sac"—a very technical piece on the growth of the yolk sac—states that a yolk sac first develops near the developing heart of the baby.

The takeaway from this: If you see a yolk sac, there was, at some point, a baby. Yes, the pregnancy could stop developing from this point and result in miscarriage, but this is not a true blighted ovum

Before you read this page, let me give you the takeaway message: Unless your gestational sac is 25mm, and you've waited one week past this mark, it may be too early to diagnose a blighted ovum.

What Is a Gestational Sac?

Keeping in mind that ultrasound measurements are not as reliable as our doctors would have us believe, they can be useful in helping us determine if there is still hope.

As I said before, the UK has some new guidelines. Let's take a look at them, shall we?

(To view these new guidelines for yourself, you can download the PDF from the National Institute for Health and Care Excellence's site. CG154 Ectopic pregnancy and miscarriage: NICE guideline)

For gestational sacs that are more than 25mm:

If the mean gestational sac diameter is 25mm or more, using a transvaginal ultrasound scan, and there is no visible fetal pole:

  • seek a second opinion on the viability of the pregnancy,
  • and perform a second scan a minimum of seven days after the first before making a diagnosis.

For gestational sacs that are less than 25mm:

If the mean gestational sac diameter is less than 25mm, using a transvaginal ultrasound scan, and there is no visible fetal pole:

  • perform a second scan a minimum of seven days after the first before making a diagnosis.
  • Further scans may be needed before a diagnosis can be made.

In a nutshell, a blighted ovum should not be diagnosed during the first appointment. If your doctor is diagnosing you at the first appointment, it may be time to find a new doctor. Whether the sac is bigger than or less than 25mm, unless there is an immediate need to end the pregnancy, an ultrasound should be scheduled at least seven days out—six days is too soon! If the gestational sac is growing, keep having ultrasounds a week apart until you reach 25mm. Then schedule one more scan a week later to verify.

How Reliable Are Ultrasound Measurements?

For years, I've talked with women who had two ultrasounds by two different techs the same day, and the measurements were very different. I've blogged about a woman who shared with me that two different techs measured the exact same ultrasound picture and got two different measurements.

When you boil it down, ultrasound measurements are not accurate enough to be used to diagnose a blighted ovum.

Is Your Doctor Scaring You Into Ending Your Pregnancy?

In that same NICE report cited above, it recommends doctors inform women of what to expect while waiting for a repeat scan, and waiting for a repeat scan has no detrimental effects on the outcome of the pregnancy.

I cannot even begin to count the number of women who have contacted me and told me that their doctors have told them they are risking future fertility, or even their lives if they do not have an immediate dilation and curettage (D&C) for their blighted ovum. My own doctor told me at both seven and eight weeks what a risk I was taking by turning down the D&C. And, like me, a number of these women went on to have a viable pregnancy.

The takeaway from this: If the gestational sac is seen, and there are no additional symptoms (high fever, foul discharge, etc.), waiting it out is not only acceptable, it is now advisable.

Why is this page so important? Because now you have something from doctors, by doctors, to show your doctor at your next appointment. You have 'proof' (besides the hundreds, if not thousands of stories online) to show you are being diagnosed too soon!

How Important Is the Date of Your Last Period?

It's not that important. Many doctors are all about the dates of your last period and, as a result, are more likely to misdiagnose you.

Taken from the website of the Office of Women's Health, U.S. Department of Health and Human Services:

"Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens."

Your doctor knows this. So, why are they still insisting on dating your pregnancy based on the average cycle?

According to that same NICE report cited above, "Do not use gestational age from the last menstrual period alone to determine whether a fetal heartbeat should be visible. Inform women that the date of their last menstrual period may not give an accurate representation of gestational age because of variability in the menstrual cycle."

Last menstrual period? Not so important. Sure, it gives a good general guideline, but unless you are almost in the second trimester, it's not a good indication of a blighted ovum.

The takeaway from this: If your doctor is basing your blighted ovum diagnosis on the fact that you are seven or eight weeks past your last period, and the baby isn't seen on an ultrasound, the doctor is wrong. It's still too early.

Are Your hCG Levels Important?

Again, hCG levels aren't that important. Generally, hCG levels seem most useful in helping to determine whether a pregnancy is ectopic or not. Once the gestational sac is seen, most doctors stop taking hCG levels because they can go up and be normal, or slow and plateau and still be normal. I've even talked to women whose numbers have declined, and they've had a normal viable pregnancy.

The takeaway from this: If your gestational sac has already been found, hCG levels won't really do much to help a diagnosis. With a blighted ovum, numbers can sometimes rise normally, and in a viable pregnancy, they may slow considerably. Your doctor needs to stop focusing on your levels.

Things to Remember About Diagnosing a Blighted Ovum

  • Make sure the pregnancy is not ectopic, and stay closely monitored if the gestational sac is seen, and an ectopic pregnancy is a concern.
  • Keep those ultrasounds spaced out by at least seven days. This gives everything enough time to grow and be seen on an ultrasound if the pregnancy is viable.
  • Monitor your hCG levels, but remember that they are really only useful in determining if you're pregnant and whether or not it is an ectopic pregnancy. Once the gestational sac is viewed, hCG levels can do many different things in both blighted ovum pregnancies and normal, viable pregnancies. Don't get caught up in your hCG levels.
  • Wait out a blighted ovum diagnosis if there are no complications. It is perfectly acceptable and even preferable.
  • Find a doctor who won't try to scare you into ending your pregnancy too early.
  • Get a second opinion if your doctor is diagnosing you too soon. Women do it all the time, and sometimes that is the way they end up finding awesome doctors.

In a nutshell, the size of the gestational sac is probably the most important key to diagnosing a blighted ovum.

The UK's Misdiagnosed Miscarriage Scandal

In 2011, the issue of misdiagnosed miscarriages came to light (in a big way) in the UK. As a result of the scandal, the UK revised their guidelines. Misdiagnosed miscarriages are very real. Our goal now is to get all doctors to realize the standards have changed, and save these babies' lives.

For years, we have been collecting stories of women who have had misdiagnosed miscarriages. In fact, on average, I hear from at least one woman a week who has gone through a misdiagnosed miscarriage. Rare occurrence? Absolutely not. And, if I hear from around one woman a week who has been misdiagnosed, how many more are there out there?

If there is a yolk sac or a fetal pole, this is not a blighted ovum. This does not mean the pregnancy is necessarily viable, though. Miscarriages can occur after these things are seen. It just means it is not a blighted ovum (and your doctor should know that).

What the New Guidelines Will Not Do

Sadly, miscarriages are very common. These guidelines will not prevent a miscarriage from happening. What these guidelines will do, however, is prevent a viable pregnancy from being ended too early.

Are you going through a miscarriage scare? Do you think you are being diagnosed too soon? I'd love to hear from you. Comment below, or message me through my profile.

Questions & Answers

Question: I got my HCG 44 then 99.8 with no cramping or bleeding. Please is there any way to save my pregnancy?

Answer: Depends upon how far along you are. Please, stay closely monitored.

Question: I had a frozen egg transfer on January 30 and got a positive pregnancy test. My first hcg result at 12dpt was 100 and 3426 at 19dpt. I had my first ultrasound scan on March 7th and the dr said the sac is empty and i should get a d&c. This would be my second d&c. I am 40 and lost hope. Can you say anything to me?

Answer: If the gestational sac is growing from week to week and there are no complications, you really should not be diagnosed before the sac is more than 25mm.

Question: I went in for an ultrasound yesterday and they only saw a sac, no yolk sac or baby. The doctor told me it could be blighted ovum because I'm measuring at 6w and 4 days when my last major period says I should be almost 8 weeks. I told the tech that my last women's exam they told me I have a tilted uterus, but she didn't take it in consideration and just diagnosed me with the blighted ovum. Should I get a second opinion regarding my pregnancy?

Answer: Eight weeks is just too early to diagnose a blighted ovum. They should be monitoring you closely with ultrasounds each week to see if the gestational sac is growing. If it is and there are no complications, the sac should be more than 25mm before being diagnosed.

I Would Love to Hear From You

Onyla on July 22, 2020:

Hi, I had a ultrasound at 8 weeks and the dr said that the sac was empty that she should of been to see what she called a baby that look like a gummy bear. As I started to get upset she asked was I sure of my dates and she stopped the ultrasound and told me she was sorry it must of been a chemical pregnancy I didn’t find out if there was a yolk or how big the sac was the only thing she said was it was empty they did blood test but I haven’t heard anything else from the dr office I’m confused and don’t really know what to do or think. Any advice will be helpful thank you.

Jayhilaria on July 10, 2020:

Hi I need answers and enlightenment too because I had miscarriage due to blighted ovum and now 6 weeks pregnant. I am now scared because there is no symptoms unlike on the first. Is it possible that it will reoccur?

Laurynb on May 04, 2020:

2nd pregnancy ever only 21 years old never had an abortion or miscarriage or even been on been birth control 1st week of discovering a Titled uterus got a Transvaginal sonogram seen the yolk sac 2nd week gestational sac + took my blood results came back with HGC levels 2500.6 3rd week again with a Transvaginal Sonogram blank no embryo growing where we can see. My dr said I could miscarry any day but I’ve just been spotting with dark brown blood. I don’t have severe back pain or cramps. My prego symptoms come and go. (Tinder boobs, very tired, nausea, etc) Could I be entirely too early to detect a miscarriage with a retroverted uterus???

Jessica627 on December 16, 2019:

Last Thursday I went in for my first ultrasound and I had calculated that I was 8 week 3 days. During the appointment the doctor could not find the fetus only the sack. He said he thought it might be a blighted ovum but wanted to wait 7 days to do another ultrasound. I don’t know what the sack measured last Thursday. I didn’t even know this was possible until that appointment. I’m so scared to go in on Thursday this week. I have not had any bleeding or spotting and before last weeks appointment my pregnancy was progressing like normal with morning sickness, tender boobs, and mild changes in moods. I have 3 more days to wait and need some help dealing with this. I find myself thinking about this all the time but I don’t want to talk to friends or family because the few I did say something already assume the worst and state sorry.

Doodoo on September 19, 2019:

Hello there

Last four days The scan showed my msd was 10.4mm and today (after 4days) the mad sac measured at 11.6mm. Both scan showed nothing but doctor already assumed my pregnancy is non viable and suggested Dn C if next scan will show nothing as well. What do you think?

Sherisse on June 12, 2019:

I have been experiencing mild cramps and spotting every other day. Faint in color sometimes and once bright red. I did an ultrasound as early as 5 weeks based on last period, but I am pretty sure gestational was 4 weeks. What was seen were plenty of fibroids ranging in size and a gestational sack. This was in the emergency room since that day the cramps were bad and spotting was a vibrant red. No baby seen, just the sack. I was urged to see my obgyn asap. I have been going to the doctor once a week for a month to check my hcg levels. They have been doubling so the doctors were not much concerned but based on the scare the doctor in the emergency room gave me because of my fibroids, I wanted another ultrasound. I finally got one today at 8 weeks but it was not good news. The maternal fetal specialist did an ultrasound and spotted the baby along with many fibroids. One huge fibroid and one that was pressing against the baby. No heartbeat was detected. The doctor is sure that I have a miscarriage but wants to wait just one more week and check again for a heartbeat before saying that I have to get a dnc done. I lost all hope at this point.

I hope you are staying closely monitored. What are the doctors saying?

Kay (author) on June 01, 2019:

Joanna, I am so happy for you. Congratulations!!! I'm so glad you shared your story!

Kay (author) on June 01, 2019:

I am just so sorry and I do hope you post when you have some news to share. Huge hug for you.

Mimi on May 24, 2019:

Hi, thanks so much for creating this avenue for people to share their worries.

I am 9weeks pregnant . I have had two encounters of bleeding and cloths coming out 2times in each occasion, both happened in interval of a week and two days. my doctor suspected Ectopic pregnancy and sent me to have three blood test every two days to determine if HCG was increase which happens to have no issues.

I sent for an ultrasound which the heartbeat was 174bpm. and the baby was seen at the normal place.

the only scary parts are my multiply fibroids which the biggest was measured 69mm at the left lateral margin.

also, Single viable intrauterine gestation, irregularity of the gestational sac 22.8mm and shortening of cervix 27mm. i really dont know what to think having prayed to get pregnant for 4yrs and now coming up with all these issues. please advice. thank you.

Joanna on May 14, 2019:

Thank you so much for creating this website. It gave me a lot of hope when my doctor gave me very little last week. I was supposed to be 6 weeks and 4 days and I had a vaginal ultrasound. All that it showed was a gestational sac and yolk sac. No fetal pole or heartbeat. He did not say I had miscarried yet but insinuated I would and that things were not looking good. I left devastated. I couldn't believe this was happening again. I just miscarriaged a few months ago and there had been no baby growing.

I found all the stories like mine here and it really encouraged me. I did so much praying and made myself sick with worry. This was not a good way to spend my birthday and Mother's day, but I believe in miracles and God is good! I have been so naseated that I keep thinking there has to be a baby growing! With my miscarriage I had none. Today I went and had another ultrasound done at a different office and there it was...the flittering of a little heartbeat. Such a beautiful picture of life! I'm so grateful to God my baby is alive after all! Never give up praying. Doctors can be wrong.

Elizabeth on May 04, 2019:

Dear Kay,

I just want to thank you for the clear, concise information here and its’ compassionate presentation. This is something that can be very difficult to find ~ and crucial for women and their partners during a time that is frightening & confusing. I appreciate having found this site while going through a similar experience and some of the reading that I did here helped me to find comfort as well as enabling me to navigate my course in a knowledgeable & empowered way. At this point in my own story ~ it does appear that our pregnancy is not viable.

(At approximately 4 weeks, my hcg levels were 47,000. Dating’s been very challenging as I’d had an IUD (Mirena) for quite awhile prior which had eliminated my menstrual cycle. First ultrasound showed a gestational sac looking to be about 8 weeks developed to be only 6, without heartbeat, as the doctor explained. HcG levels that day were 59,000 ~ two days later dropped to 45,000 and another two days later to 39,000 ~ at this time I’d opted to stop testing HcG levels. Nine days after the first ultrasound, we returned for the second. The fetal pole was gone and there did not appear to be a yolk sac. When the PA told us that the gestational sac measured 8 weeks 3 days, I asked specifically if it measured more than 25 mm ~ it did.)

It has meant more than I can express to feel armed with knowledge and for that I am grateful. Thank you for your efforts here!

My SO and I have opted to allow the miscarriage to happen naturally, what is sometimes termed “expectant management.” This part of the process, too, is hard and ~ once again, I’ve found ~ made more challenging, perhaps, by the assertive manner in which the medical term were pushing their opinion regarding the Right Way to proceed (Invasive Medical Intervention Immediately). I would like to share this link as I’ve found the following information to be sensitive & compassionate as well as extremely helpful in fully understanding my options as we cope with coming to terms with what we can now be fairly certain is the inevitable miscarriage. I hope that it may help others.

All my love to all the women here ~ stay strong. I will post again when our baby’s time is right and we are able to hold that little angel in our arms at last.

Kay (author) on March 30, 2019:

Hi Sarah. Levels can fluctuate with bleeding. Stay monitored. Hard to say what is happening. Hugs!

Sarah on March 28, 2019:

So here it goes

We had a frozen embryo transfer on the 18/2/19 tested on ghe 1/3/19 we was over the moon after 7 yrs of trying and this being our first positive that was short lived when on the 16/03/19 i started bleeding had an emergancy scan on the 18/03/19 should have been 7 weeks but sac was only mesuring 5 weeks had bloods also done this day and there were 6465 also sac mesured 7.2 had bloods again on the 20/03/19 and they were 7289 so was booked for another scan went for that scan on the 26/03/19 and sac was 10.2 they said there expecting my bloods to drop and it was a BO but bloods came bk at 9468 and have booked me for another scan next week im so confused

Jasmin on March 18, 2019:

Im 7weeks2days based on my LMP. But my sac size 16.1mm stated that Im only 6w2d. My transv impression was anembryonic pregnancy since the doctor didnt see any yolk and hb. Only the gs. Is that really a blighted ovum?

Sara on March 13, 2019:

I m 7weeks pregnant but only gastational sac is seen that is about 27mm but no fetal pole heart beat just empty sac..and I spotted at that day.what does it means..I have to wait

Kat Tatro on March 11, 2019:

I am 8+5 weeks according to my last menstrual period. I went into my Dr for a ultrasound because of some slight bleeding/clotting. They wouldn't really let me see the ultrasound pictures, but the few I did see seemed empty. I know what to look for having 2 healthy pregnancies already. After talking with the Dr, she said to wait 1 week for another ultrasound to see if there is progression. I'm very nervous and worried. She then discussed D&C and other options, saying she believed it wasn't a viable pregnancy. I have another ultrasound schedule a week out. Should I hold off on the D&C even after the ultrasound since I will only be a little over 9 weeks?

Kristen Miller on December 28, 2018:

I’ve been having brown spotting so had early ultrasounds. First one at 6 weeks showed gestational sac but no yolk. HCG was diagnosed as high for gestational age. Today at 7 weeks showed a yolk sac but no fetal pole. Was told it may be an an embryonic pregnancy and to come back next week for another ultrasound and to discuss d&c/pill options. Have been crying my eyes out all day.

Kay (author) on December 13, 2018:

Huge hugs for you. Please, keep us updated!

Maybaby1988 on December 11, 2018:

Currently going for weekly scans. Had 2 miscarriages previously, one at 6 weeks, the other was diagnosed as missed miscarriage at 12 weeks which required SMM.

3rd pregnancy I forced an early scan (much to DRs persistence that its too early).

First scan 2 weeks ago showed 4!!! Small empty sacs and they think I’m not as far as they originally thought (based on my period dates they predicted). A week later, scan shows all have grown, not the same size and not loads but they wont diagnose as they can’t be sure theyre blighted.

Dr gave me the option of managing miscarriage or another scan in a week; hard decision but as they couldn’t be 100% I couldn’t make that call to start miscarriage procedure.

Still have many of the pregnancy symptoms but then with 4 sacs, I’m sure my hormones are all over the show!

Would be interested to hear to see any other comments from others who may have been in similar situation, ie multiples. Do they take longer to develop?

It may just be that I need to go for further testing as this would be my 3rd miscarriage out of 3, only time will tell.


Ashley on September 25, 2018:

Hi there, I have PCOS and before having our daughter I hadn’t had a period for 15 months. She is now a year old on Sunday and since giving birth I have had 3 periods, so when my pregnancy test came back positive on August 25 th we were so excited but I did not know how far along I was because my cycle is so so unpredictable. I decided to go to a private ultrasound and was told I was probably only about 5 weeks and she could only see a sac, so I decided to come back a week later to see how things would progress. A week later I returned and as she was doing my scan I could see the sac was much larger but it was empty. She proceeded to tell us that it was likely a blighted ovum and what my options would be and how sorry she was, she proceeded to tell us about her own miscarriages. To us, this really felt that it must be over. We both left crying, we were heartbroken. I went to my doctor the following Monday, my doctor said she does not trust those private ultrasounds and that a proper vaginal ultrasound at the hospital was the only way to know for sure, she tested my hcg and it was as she said very very good and rising went from 27,000-48,000 within a couple days. My ultrasound appointment however wouldn’t be until two weeks later(this coming Thursday) this has been the biggest roller coaster of emotions. We don’t know how to feel. I have felt depressed these past couple weeks being in limbo and not knowing if we have a baby or not. I have no spotting bleeding or cramping at all, but I also have hardly any symptoms unlike my first pregnancy where I was a complete wreck with every symptom under the sun. I am so confused and angry at myself for getting such an early scan. I am also angry with the private ultrasound lady who had us grieve a loss that may not be a loss. She is undiagnostic so this really was out of line. I wish she had just said sorry I can’t see anything abdominally this early you should get a vaginal scan at your doctors. This would have saved us so much pain and anxiety waiting to get to this next scan. Sorry for the long post but I have been searching every possible site and story trying to find a story like mine that has a happy ending. I will keep you posted on my scan this Thursday. Fingers and toes crossed!


Concernedmama on September 14, 2018:

Today it was my 2nd ultrasound. Lmp 7/19/18. Irregular cycles. Supposed to be 8 wks 1day. The nurse only seen the sac nothing in yet. No yolk or fetus pole (i believe thats what its called) yet. Measured 19 millimeters today. My first ultrasound it was at 6 weeks no yolk either sized to 6.4mm then. I have been on progestren so the doc said i wouldve probably misscarried sooner if i wasnt on it. My levels have been growing. Ive been very nausea still. But my doc was very pushy for me to get the d&c so they can understand why. Since this wasnt my 1st misscarriage. Had i known docs can be wrg about this sooner maybe my last one could have been saved. But now its different. I dont feel like there right. So ive been doing my research & found hope! Im not even 25mm yet. For them to push me to decide. Im an emotional wreck right now. Im gonna wait it out. Im also gonna stop taking them progesterone pills. I hope she is wrg. Im hoping my next ultra sound is good & they find my baby. I dont want to go through this anymore! May the Lord be my side & make a miracle happen. I believe! Prayers!

Kay (author) on September 14, 2018:

If there are no complications, you could ask for a follow-up ultrasound one week out. If the sac is growing and not yet 25mm, it may be too early. Stay closely monitored! (((hugs)))

Jam Montoya on September 13, 2018:

So 2 weeks ago went in for my first prenatal visit, when DR did transvaginal scan she said I was as far along as I thought so she scheduled me to come back in 2 weeks. Yesterday was my 2 week schedule and she informed me that my pregnancy stopped growing and I have any empty yolk sac. I went today to get another ultrasound sound as she said her equipment is not the best but the ultrasound today show the same thing. I still feel really pregnant and would die if I knew the baby was still alive and I went on with the D&C. Don’t know what to do this would be my third miscarriage and I have PCOS as well. Any suggestions I need help making the right decision

Theresa Calvillo on September 06, 2018:

So im 30 years old and this is my first pregnancy, I was really excited when I found out I was pregnant considering I had been trying for about 2 years. First off, I was supposed to be at 10 weeks, but according to my ultrasound my sac messured at 5 weeks so there was no yolk sac or fetal pole, I was reassured that it still might be too early to see anything, went in a week later for another ultrasound, still no yolk or fetal. 6th week and six days and I got a new doctor (which I hated btw) another ultrasound and still nothing. First off I felt as though my doctor was completely unprofessional and insensitive. Her response to my empty sac was "na girl I don't see anything." I'm sorry but are you fucken kidding me! Then she proceeded to tell me that we should have seen something by now to not get my hopes up. That if we don't see anything soon, we're prob gonna have to do a DnC. My hcg levels are high and still rising. We are still gonna do more blood work and another ultrasound next week. I'm still hoping for the best. This has been such a horrible, emotional, and heartbreaking experience so far. This is not how I pictured my first pregnancy to be. I have no bleeding, no severe cramps, if anything I feel pregnant, nausea, sometimes vomiting, sore breast, tired, emotional, mild cramps etc... I'm just hope everything turns out for the best :/

Michelle Rimmer on August 25, 2018:

From my last period i should be 10weeks but i know dates can be wrong. I started having the slightest spotting which sent me to the emergency department. They did a scan and hormone levels. The scan showed a sac but it was empty and my hormones was 18000. Was told pregnancy unknown!! Then had hormone levels checked 48hrs later they read at 21000. Then had a scan 2 days after that which showed the same result sac was 17mm. I was then told they was almost certain i had a early miscarriage from the 2 scans 4 days apart and the 2 hormone tests. I was devasted. Told to do another hormone test and they would expect it to drop dramatically, it didnt it was at 20000. They then called me a day later and said doctor wants to do another scan on that friday. I turned up and they had cancelled my scan because they read i had a early miscarriage. Then they realised i shouldn't have been told this because they didnt leave enough days inbetween the 2 scans!! They re-scanned me still nothing in the sac but it had grown to 21mm. I was told by a doctor i am a unusual case?!! According to my hormone levels they should be seeing something in the sac but there not but they cant say i have miscarried because i am not 25mm in size!! I was told they are certain i will miscarry 99% doctor said. It may happen its not out of the question but they shouldnt of told me that devastating news when errors were made!! I have another scan booked for 2 weeks time so got to wait and see.

Alexa Moore on March 17, 2018:

I was diagnosed with blighted ovum but there was a yolk found but my sac was an irregular shape. I know I'm too early but I worry that since there is a yolk am I having a missed mc instead and can I let this pass naturally? I don't want to have a d&c. I have been spotting everyday since with some tissues in toilet when I pee. Cramping too but my cervix still seems to be closed and symptoms come and go. Not sure what to think.

Thank you for sharing so much information about blighted ovum. I suffer from endometriosis, and my husband and i have been trying 3 months short of a year. We were getting prepared to start infertility treatments if we didn't have any luck the next three months, but I found out I was pregnant 7 days ago. 3 days ago my husband took me to the hospital b/c of heavy bleeding. We thought i was miscarrying, but the doctor said everything looked great. Yesterday, they tested my HCG levels, and told me that if I wasn't having the on and off heavy bleeding (it happens once a day for about 20mins to an hour, then i spot on and off throughout the day) they would think it to be a normal early pregnancy. They say I'm about 5 - 6 weeks, but i think I'm around 4 weeks as far as when conception took place. I had to go to a follow up ultrasound today, and my doctor told me there was a sac, yolk, but no pole which tells him it's probably a blighted ovum. I have another ultrasound in a few days to see if anything has changed. I'm having a really hard time emotionally dealing with this. This is mine and my husbands first pregnancy, and this last week has just been an emotional roller coaster with what seems to be no ending. My husband sent me your story about your misdiagnosed miscarriage and it gives me some hope that there's still a possibility that we could have a healthy happy baby. I don't have any questions, it's just nice knowing that there is hope and that other women go through this often.

(((hugs))) to you. Because a yolk sac is seen, this isn't a blighted ovum but that doesn't mean the pregnancy is viable either. It sounds like the sac is just about 25mm so you should have your answer. I do hope you got that second opinion and have been staying closely monitored. (((hugs)))

Hi Kay,

I came across your page and I found it very helpful and informative. I have a situation here and I hope you can give me some advise on what to do. I was diagnosed of blighted ovum by my OB. I had PCOS so my OB advised mo to take folic acid and metformin. After having a regular monthly period for 6 mos me and my husband decided to undergo a fertility program. We started taking clomid on October 2017. Got no luck on October and November 2017. I was waiting for my December 2017 period but never came so I thought just a missed period. Jan 01 2018 before taking a bath I noticed a small drop of blood on my undies so I though its a spotting and my period will start that day. The next day I noticed that there was no bleeding nor the spotting and I can feel a little pain on my belly botton. I waited until Jan 04 2018 and took HPT and to my surprise 2 bright red lines showed up, so I immediately scheduled an appointment with my ob and she asked me to have my 1st scan on Jan 11 2018. Results are LMP AOG- 6w2d UTZ AOG- 5w2d. With gestational sac and yolk sac but no bay seen no HB with corpus leteum on the left.My ob says it's okay and have another scan after 2 weeks. Jan 27 2018 I had my 2nd scan and results are LMP AOG- 8w4d UTZ AOG- 6w3d with irregular gestational sac and yolk sac, no baby seen no HB, with subchorionic hemorrhage. My ob gave me Isoxilan. By the way I am also taking Heragest. My ob says it is weird not to see a baby so she asked me to have a 3rd scan. I had my 3rd scan Feb 09 2018 and the results are LMP AOG- 10w3d UTZ AOG- 6w4d with gestational sac and yolk sac no baby seen no HB. My gestational sac mean sac diameter on the 3rd scan was 2.3cm. My OB says that I have a blighted ovum and wants me to have D&C on that very same day but my husband refuse. My husband wants me to have a 2nd opinion with a different doctor next week. We don't want to give up yet and we are still hoping that this is a viable pregnancy. Any idea what going on with my results? By the way this is my 1st pregnancy and we've been waiting for our lil sweet pea for almost 3 years. I am 36 yrs old and my husband is 33. They said that I have a high risk pregnancy because of my age. Please help Kay or any advise from others who have similar situation with mine. We are still hopeful to see our miracle baby. Thanks in advance

Kay (author) on February 03, 2018:

Hi Kara. I love that your doctor said that you should wait until the sac is 25mm. The word is getting out there! By now I'm sure you have your answer. I do hope they found your little one. (((hugs)))

Melissa on January 24, 2018:

Hi, I took a pregnancy test on December 17,2017 and found out I was expecting! This would be My third child!! I was so excited and couldn’t wait to tell everyone!!! I went to My first doctors appointment and she wanted to do a bedside U.s. we seen the sac but no baby. So she scheduled me an appointment a week later (today January 24,2018) there was no baby. I’m totally freaked because my first two babies where healthy and normal. I keep thinking about Blighted Ovum. I guess I’m just trying to get advice or story’s like mine. I’m so upset but trying to keep positive thoughts!

Millie W on January 24, 2018:

Hi I have a question. I’m almost 6 weeks pregnant and I went in for an ultrasound yesterday. I measured great and had a great yolk sac but they couldn’t see the baby. My ultrasound tech said you have a very tilted uterus. She was so young and so gentle like she was afraid of hurting me. I go back in a week, is there any advice I can give her to help see the baby better?

Kara73 on January 16, 2018:

Hi. I was diagnosed with a BO at 6 weeks via transvaginal u/s, and had another one at 7 weeks that showed the GS had grown from 16mm to 21mm. The sac was initially empty, but then it looked like there was something in it that was blurry at the 2nd u/s. The tech wrote it off as "probably remnants of the yolk sac," only the GS was EMPTY the week before and there was NO yolk sac there. The tech said it was "non-viable." However, the Dr. said we need to wait to 25mm to diagnose a BO. We go back in one week, which will put me at 8-weeks. My sister has a tilted uterus and that was never mentioned to me but I've read it's genetic. My son was born in the posterior position and I've read that's highly correlated with retroverted uterus. I'm wondering if I should wait until 9-10 weeks for the next u/s, rather than go at 8-weeks. I had a D&C for a MC at 14-weeks and it really messed up my cycles for 16-months, so I really don't want another one. This is such a hard experience. I'm 44 now and have no time to waste, but don't want to make a terrible mistake. I got pregnant this past August, only to miscarry at 8-weeks, but it was a clear miscarriage since the GS and YS started to shrivel. This just feels different. Plus, I just don't understand how one week there's nothing there, and the next there's something blurry there. Oh, and the Dr. said my uterus is perfectly intact and shows no signs of miscarriage. She said she's only seen "something indiscernible and blurry" in the case of twins, but that we would know by now if it was a twin pregnancy.

Karla on November 02, 2017:

I am 10 weeks and 1 day pregnant, 2 days ago I had an US and the Dr told me the baby only meassures 6mm, and that it should be 3cm already; hcg= 19,000..told me it could be a blighted ovum, but it's something there, it is too small and it doesn't have a heart beat with the transvaginal very fancy new equipment. I'm having another ultrasound in one week (11 pregnant) the waiting it's killing me, I don't know what to do, if I can grief or not,they put me on bed rest for the week so I am here reading as much as I can so I can be "ready"

Zana on October 16, 2017:

I found out I was pregnant through a home pregnancy test sept. 12 and had my last period august 17-24/25 they did my first ultrasound around September 26 and they didn’t see anything at all no gestational sac or anything. Ff to last Tuesday October 10th we seen a gestational sac and they said I have a tilted uterus. Also said I had a subchoronic hemorrhage and no fetal pole or yolk sac. Fast forward to today another ultrasound and still just a gestational sac but no yolk or fetal pole nor a heart beat. They called and said it’s not viable and when I asked to wait until I was ten weeks just to be sure they said “we can give you until Friday?” I haven’t had any bleeding or cramping so I’m going in at 8:45 in the morning to tell him I am waiting or finding a new doctor even though they’ve already prescribed me clomid. I don’t have much hope at this point but I feel like I at least deserve to give myself and my baby a 100% fighting chance. Any advice.

Kristin on October 14, 2017:


I recently did IVF (so I have accurate dates).

I have been told by my doctor that I have a non viable pregnancy based on my low hcg numbers. I went for an ultrasound at 6 weeks (hcg 1472) and they saw the start of a gestational sac measuring 2mm. I then went back for another one at 7 weeks (hcg 8355) and they saw a 8mm sac but no yolk or fetal pole. They are saying it’s not a viable pregnancy. Is it common to not see a fetal pole at 7 weeks when your are sure about dates because of IVF?

Thanks so much for your advice!

Kay (author) on September 30, 2017:

Oh, I am so sorry. I don't like when doctors push D&Cs. I don't know what you found at that next appointment but I do hope you got better news. You are diagnosed too quickly.

Kay (author) on September 30, 2017:

I am so sorry you are going through this. If the sac is growing and they are sure it is not ectopic, they should monitor it week to week until it is more than 25mm to verify a blighted ovum. (((hugs))) to you.

Pashaia Brooks on September 23, 2017:

I went to the health department on aug 14,took a pregnancy test and it was negative. Aug 18, Something in my gut said "go ahead and go to the dollar store and get a first response" so i did.i took my first p in the am to see what that does. since that was the instructions & the Box claim to read levels of the Six-Day earlier than the normal test, soon be Hold I was pregnant I couldn't believe it. A week later made a doctor's appointment. Same day My blood drawn I got a call later on that . The nurse said my progesterone was low immediately the next day he offered me progesterone. sent it to the pharmacy. A week later came in for my first sonogram this is September 1st they could not see anything no gest r zip. Sep 6 came back,ULTA sound agian nothing. September10th I came back seen nothing. At this time the doctors was going off my menstrual. And because they didn't add up with the the ultrasound. The first thing that came out of his mouth that I was having an ectopic or he was in fear of me having an eptopic pregnancy because of the fact that they don't see anything it might be in my tubes. I was scared confused not to mention I had a miscarriage back in May so I kind of trusted work and I was really hoping that this pregnancy will come thru. Anyways I didn't trust that!!! so I ask a doctor to do another sonogram before I made my choice and for him to check my blood again and he scheduled back in a week which was September 16th. the sonogram but he said well I think I see a little Sac but I'm not for sure. the doctor had me come back in 4 days which was there the end of the week. I did did another scan gestational sac grew. he ruled out the eptopic and said I was having a viral pregnancy. Had me back in a weak again back September the 18th the ultrasound still not seeing anything inside the gestational sac. I went back again September 21st Sac had grew the ultrasound lady measured me to be 6 weeks 3 days. I have no yolk Sac or fetal Pole. Now they're calling. Blaiten ovrom or whatever crap I am so scared . I'm so confused he tells me when I come back next week and there is no heartbeat fetal Pole or yolk sac I need to be prepared for a DNC. I assume im just to early ? I dont know tho. my cycle have alway been Being irregular . The month before I got pregnant I had a 8-day cycle.From July 18th to the 28th from.+ I don't know what to or even how far I really am . am confused I don't know if I'm having another miscarriage or what what are my hopes of keeping my baby? So do you think I'm too early I'm very confused I would appreciate if somebody got back with me Shaybrooks418at I appreciate you listening and I hope this makes sense

Jessy on September 19, 2017:

Hello, my story is a bit complex. I had the Adiana procedure (permanent birth control) 5 years ago. Most recently I had a missed period followed by two positive pregnancy tests. I had an U/S on 9/15/17 which based on my last LMP of 8/28/17 would put me at 7 weeks. However I have had irregular periods for the past 5 months and I am most certain the week I conceived, so I believe I was just about 5 weeks long. The doctor ( this was the doctor who did my Adiana procedure) was quick to diagnose me with a blighted ovum. He said there should be an embryo and heartbeat present, but he only saw an empty sac. He never gave me the measurements of the gestational sac. Then he quickly wanted to take me to the OR this week on Friday to remove the sac. I was very hesitant and stated I would rather have my body pass it naturally. I felt like he was pushing me to go to the OR to remove the sac or other option would be to also remove the tubes via laparoscopic surgery. Then he said; "well you are a very busy person too". He knows that I am a healthcare provider. I felt very angry after leaving. I have now picked another doctor who will see me on 9/27/17 for another U/S. I am very anxious and hoping for the best. Me and my husband would like to have this baby.

Kay (author) on September 15, 2017:

(((hugs))) to you. Often times doctors seem to do a repeat ultrasound one week later to verify there is no growth. There have been women who have seen those heartbeats again but others who have gone on to miscarry. I do hope you get better news.

Lauren on September 12, 2017:

Hello I had a ultrasound two weeks ago and was told I was 6 weeks and a strong heart beat of 120. I went back on9-11-17 and they could not find a heart beat and when they measured the baby it was still at 6 weeks he told me I had a miscarriage but I have not had any signs or symptoms o a miscarriage I still have sore breast and exhausted all the time. I go back tomorrow for a repeat scan. But after reading so much and hearing stories of women who this has happened two at 8 weeks and then thefind the heart beat I am lost to o ow what to think or know. I also have kaiser so if anyone know how I can get a second opinion please do let me know

Isabelle on September 02, 2017:


The hospital called me last wednesday to go on last thursday to the clinic for having an abortion.

Even before I went to the doctor one last time to confirm the blighted ovum.

After the hospital Phone call, went to the doctor and There was a yolk sac and heartbeat. Turned out I m two weeks behind. The gestational sac stayed from week 5 till 7 the same with no development, only at week seven the size was bigger 24 mm, but with nothing in iT...

My dates are for sure correct. Late ovulation was not possible. Only had 3 times sex and used ovulation tests. In stead of 8 weeks I m now 6 weeks.

Hope slow growth can t do any harm.

I do not have a tilted uterus.

So iT is possible! According to the standards of the size of the sac they had iT right to call iT a blighted ovum...

Science is not everything apparenteley.

Just hoping that the slow growth is no sign there s something wrong.

Isabelle on August 26, 2017:

I had aan ultrasound at 5 weeks from my lmp and at 7 weeks. At 5 weeks gestational sac was 0,89 mm. At 7 weeks i don't know. Both times nothing visible, online an empty sac. Blood at 7 weeks was good, hcg 39000. Doctor told me i shouldn't think that i'm pregnant anymore. Next week thursday Again ultrasound at 8 weeks. I ovulated for sure the 18th of july and do not have a tilted uterus for Sure. Since I know I feel like having a sort of menstruation cramps and a little lower backpain. Don't know if its psychosomatic or what to think anymore.

Cau on July 21, 2017:

After my 2nd IVF implantation, with 7 weeks pregnancy I went for my first scan and I have received the sad diagnosis of blighted ovum, my dr couldn't find any sign of embryo although I had a big gestational sac... he suggested to go for D&C in 1 week , I went to my second doctor 1 week after this diagnosis and surprisingly she found a very small sign of an embryo! I'm very confused now... so it means that it isn't in fact a blighted ovum?? My second dr asked to wait 1 more week and I'm in panic here , I dont know what will do if she suggest the same as the previews dr, I'm 41 year old and wish so much that baby..

Would be possible a little embryo really start developing after so many weeks? Seems to you its a viable pregnancy? Thanks for any help

Kay (author) on July 15, 2017:

I am sorry you are going through this scare. Generally a week after a yolk sac is seen, a baby will be seen if the pregnancy is viable. (((hugs)))

Kay (author) on July 15, 2017:

This *could* be a miscarriage but sometimes numbers slow, plateau, or even drop temporarily. You should get them checked again to see what is happening. Many women cramp during viable pregnancies so that may be nothing. (((hugs)))

Melissa Garcia on July 13, 2017:

I have a retroverted uterus and I had an ultrasound at 8 weeks. They see a yolk sac and tell me it grew just a little bit in the past two weeks. I am positive about the day of conception. They don't see a fetal pole or a heart beat. I've had a miscarriage before but this just feels different. I'm going to have another scan one week from now and then hopefully decide what to do. I'm honestly losing hope but I have a glimmer left.

Falyn Richmond on July 09, 2017:

So I got my blood test done two days ago and it was at like 112 and than today I went back in and it was at 130 so yes doctor said I'm having a miss carriage but than he said my cervix is closed. And I'm having no spotting it cramping and this is my second pregancy. Please help me

Kay (author) on July 08, 2017:

Not sure what you'll find but a second ultrasound (done by a tech!) is a very good idea. Keep us updated. (((hugs)))

Jay on July 05, 2017:

I was seen by OBGYN on July 3 and was measuring 8 weeks 5 days and my gestational sac was 35 mm. The doctor was sure I was going to miscarry and told me the steps to take. She offered me a second ultrasound because I haven't experienced any abdominal pain or bleeding during the pregnancy. I did have a large fibroid in the scan as well. Has them happened to anyone? I'm getting a second ultrasound done; however, they didn't seem hopeful at all.

Jenny on June 09, 2017:

I did an ultrasound tummy scan at week 7 but there was nothing visible. The doctor gave me a vaginal sonogram instead and estimated the pregnancy to be at 6 weeks 2 days based on the embryo size. The embryo measures 5mm and there was a heartbeat. The hospital in Singapore KKH scheduled me to do a scan in 3 weeks time and at 9 weeks 4 days the fetus size is measured at 6.5mm using a tummy ultrasound device this time. The nurses said they couldn't detect any heartbeat on the tiny white patch and looked worried. They told me the doctor will explain what's happening. I thought it's normal as the fetus is too tiny and they did not detect anything as well last time. I did not request for a vaginal sonogram as I was afraid the radiation might be too strong and harm the fetus. I rather not hear any heartbeat than risk harming my fetus again. The doctor finally saw me and based on the scan report, she said I had a miscarriage. I told her I had no bleeding or cramps. I still feel nauseous the day and slept 12 hours the day before. The doctor said it was a missed miscarriage since the fetus has stopped growing and there wasn't a heartbeat. By now the fetus should be around 2-3cm not 6.5mm. She thought I was in denial and recommended me to do the D&C procedure. I refused. I said I will let my body do its work of flushing the tissues out. I am still wondering could the ultrasound be wrong? Did my fetus really die at week 6 day 5? Did the vaginal sonogram radiation cause the fetus heartbeat to stop? I had no miscarriage symptoms at all. What should I do?

Amanda on June 07, 2017:

I am currently pregnant I am 40 years old. My hcg is 5300 I have had 3 ultrasounds all within days of each other. My obgyn just called and said" let's give thus until Tuesday and if nothing is seen in scan we need to terminate" I am in no pain, no bleedibg. I am at a loss. I refuse to take something that will terminate this pregnancy unless they can prove to me without a dought that my life is at risk. My lmp was May 11, 2017

Kelly on May 15, 2017:

Hi, I am currently 7 weeks and 5 days pregnant.

My Obn-Gyane cannot find the heartbeat of my baby. or see the baby on the ultra sound.

He has taken blood to check my HCG levels. If the levels have drops to half then what it was previously I will need to go for a D&C. He said it could be a Blighted Ovum. I am so scared.

I dont know what to do.

Jackie on May 06, 2017:

My comment below... And, my hcg quantative beta was 44 today. I'm so beside myself in this emotional rollercoaster.

Jackie on May 04, 2017:

Kay, first, I am such a reader. I have always done so much research in everything I learn, find interest in it need answers outside the box. It has certainly been helpful advocating, and improving all I do, usually for others. With that said, I like clear information, and have read much that you've researched a
