Up until the last time I had sex, I always used protection. As things go, I was on my period and thought it ended, so me and my boyfriend had unprotexted sex because it's unlikely to get pregnant right after your period. There wasn't any blood or anything. When I got home about an hour later, I realized I was still on my period. Scared out of my mind, I made a few phone calls and got the morning after pill the next day and took it. About 4 days later I found what would seem to be on my period again. Should this happen? Did the pill work? Was I pregnant and the pill worked? I need help. ASAP! Please?
