Me and my girl of 2 years usually have unprotected sex kind of foolish I know, but I usually just pull out whenever I feel I'm going to ejaculate, we don't see each other that often because our work schedules are always conflicting. So it's not all the time we have sex, on one incident I didn't pull out and ejaculated inside of her. I went to the store and bought plan B because I was a little worried she could get pregnant because I never finish inside of her. Within 45 min she had taken the plan B but then we had unprotected sex again like we usually do where I didn't ejaculate inside of her within 10-20 min is plan b still effective because the time of her taking the pill and sex so close together?
