Hello, I'm an 18 year old girl who took part in unprotected sex last month on the last day of my period. My partner ended up finishing up while we were still going at it, and I went to the pharmacy and took the next choice morning after pill 8 hours after the accident. I bled for about two weeks off and on after I took the pills, and now, nothing. I expected my period about a week ago. I've taken four pregnacny tests over the course of two weeks (Ones that you can buy at any store), and they all test negative for pregnancy. I'm going to the gynecologyst on tuesday for a regular check up, but I'm worried I might be pregnant. I don't know how accurate those at home tests are.
