Two days ago I had sex with my boyfriend and we ended up going through 3 condoms that night. They were ones I got from college so I think they cheap ones because they kept rolling up and bunching. The first one bunched up so we used another one, that one fell off and we thought it fell off in the sheets so we used a third one and that one ended up bunching too. I didn't have anymore so we just used the pull out method. The next day I showed and then went to Work. When I got home I went to the bathroom and felt something and discovered I had a condom in me! I was I'm there for over 10+ hours and I didn't know. It was the second condom we thought fell in between the sheets. Is it possible I could get pregnant from that?
