Yesterday I had sex with my girlfriend, we used a condom that didn't break or slip. When I came I didn't inmediately pull out. When I pulled out I took off the condom and threw it away and made sure to clean myself before any other skin contact with my girlfriend. She's NOT on the reg pill so she does ovulate. Anyways, just to make sure I got her emergency morning after contraception pill. It was a 2 doses pill and she took the first one about half an hour after we had sex. About 6 hours after sex her period started, though it didn't have much blood, then, a few hours later, it stopped. Naturally we're concerned, does the pill she took work if her period started that same day? Why did she stop bleeding? Could it be because of the pill?
