Okay well... I took the morning after pill the day after me and my boyfriend had sex, the condom broke so it was to be on the safe side. The condom also had sperm killers, or something like that. Three weeks later I too a pregnancy test and it came out negative. It's been two weeks now and I'm due on my period. But, I still haven't gotten my period. I show no signs of being pregnant, but still. I'm scared.
