Someone please help me. I'm very confused as to what is going on with my body. This month on the 15th I had my normal period for 6 days. The day after I ended my period I had sex with my boyfriend and he felt the condom break, as he felt it snap he pulled out and came not in me but on me. Just to be safe I got a plan b pill the next day which was this Saturday. Tuesday I was getting strange cramps I normally don't get but I ignored it. Then yesterday I started bleeding a little bit but it was mostly brown, I know gross. But now today it's turned to blood. I took plan b before and this did not happen. I also think since I had sex the day after my period I might've been fertile? Does that have anything to do with this? Or is this implantation bleeding? Help.
