No, not yet, but you should call one! Call your general practitioner (or better yet, your gynecologist) and let them know you're two weeks late for your period but apparently not pregnant. They may want you to come in for a blood pregnancy test since for some women these seem to be more accurate than urine tests. Even if they don't want to see you, they'll have a record of the late period so that if it continues they're aware of when the issue started.
Don't panic about a late period, remember there's a lot of pretty harmless reasons, besides pregnancy, to go through this including:
- Late or missed ovulation. A late or missed ovulation means you'll be late for or miss your period since you need to ovulate to get a period.
- Stress. Stress can delay your ovulation and cause a late period.
- Illness. Are you getting over a cold or stomach bug? Viruses can cause your ovulation (and thus, your period) to be delayed.
