Me and my girlfriend were having sex. I didn't realize the condom ripped for about 5 minutes. I didn't ejaculate inside of her. However there was pre-ejaculation in the condom and some may have got inside of her. This was three days after she got off of her period and she has been on birth control only for a couple days tho. It's too late for the day after pill. What are the chances she is pregnant? What should I do?
