Okay so about 3 weeks ago, my boyfriend and I had unprotected sex, but he pulled out but it was next to getting in me. So about 45 minutes after we decided to go get the pill just in case, and I took it and I got all the normal symptoms (nausea, breast soreness, ect.) and then that next weekend (we did it on a Monday) I started bleeding a lot for about 3 days, then it stopped. today, I was scheduled to get my peruod and never got it, I don't really have any symptoms of being pregnant, I think it's more PMS, sorry to bother you guys, but any advice? Thanks so much
