Hi, I had the medication abortion pill on sept. 19th, I had unprotected sex 2 weeks later, before my 3 week check up. I took the morning after pill the day after I had unprotected sex. Came on my menstrual two days after, was still on my period the day of my check up. My ultrasound was normal and clear but my pregnancy test was positive. The doctor cleared me, well two days after my period I took another test and its still positive. Whats going on?
