Missing Period After Taking Ipill. Pregnancy Test Negative. Should I Be Worried?
It is not suprising that the pregnancy tests are negative. My guess is that you took the pills appropriately within 72 hours of unprotected intercourse. They are considered very effective. Then, when your period was late, and at the time that a test would normally turn positive, the test was negative.
One effect of the emergency contraception is a delay in ovulation and a resultant delay in your period. This is an effect of the hormones that you have taken for emergency contraception.
In your case, I would recommend to a patient in a similar situation to check a pregnancy test weekly until you get your period.
I hope that this helps. Please ask if you have any followup questions.
