Okay I'm doing my very best to not panic and it's not going so good. So I recently got off my period exactly a week ago (last sunday) and my boyfriend and I wanted to try something new. It was our first time having sex the day after (Monday). He used a condom and it broke. However, he did not ejaculate at all. I know that pre cum can get you pregnant as well so we decided to purchase a Plan B, just to stay on the safe side. I took the Plan B about 7/8 hrs after we had sex. On Friday (3/4 days later) I began to bleed. I figured it must be spotting but a couple of hours later, it began to feel like a period. It can't be my period since I got off of it exactly a week ago. Any ideas what this could be?
