Missed Period & Negative Pregnancy Test: Possible Pregnancy After Emergency Contraception?

If you had unprotected sex and then missed your period, it is possible that you could be pregnant. However, taking hormonal birth control pills, such as emergency contraceptive pills (ECPs), may affect period regularity, and pregnancy tests may yield negative results in early pregnancy or may require repeat testing for confirmation. To be certain, I recommend taking a repeat pregnancy test in a few days to confirm if you are pregnant. It is advisable to consult with a healthcare provider for an accurate diagnosis.
