Hello. I had unprotected sex with my boyfriend on June 13 during my period. I have been on birth control for about three years now and take it very regularly. On July 2 (about three weeks later) I began to see blood on the toilet paper when I would wipe. The blood was brown, pink, and some red. This lasted until July 6. Now when I wipe it is completely dry, which is irregular for me as I usually always have wetness when I wipe. I have no breast tenderness. I had cramps for a few hours on July 2, but nothing since. I have not had any morning sickness or stomach issues. I just began taking aderall again that weekend so I have lost my appetite (a common side effect of the medicine). Sometimes I find myself sweating and having hot cheeks, but no temperature. I took two early detection pregnancy test on July 4 and they both came out negative. This was to be five days before the start of my next period. I am wondering if the bleeding was implantation bleeding and I m pregnant? I have read online that if you are on birth control it is a low percent to get pregnant. I have also read that having sex on your period it is highly unlikely to become pregnant. However, the time of implantation bleeding is supposed to come a week before you would have your period, and that is when the bleeding started for me. Please help! June 13 - unprotected sex during menstruation July 2 - bleeding begins July 4 - two negative pregnancy tests July 6 - bleeding stops July 9 - next expected period (according to BC)
