I don't know if I'm worrying over nothing but I could really use some advice. About two months ago my girlfriend and I slept together in the same bed but didn't have sex. She was naked and I had sweatpants on. I think it was around the time she would be ovulating. We did a little heavy petting but I didn't ejaculate until the morning no where near her. Is there any possibility she could get pregnant from precum on my hands or anything (not that I know there was). She has had two normal periods since then but I still worry because I read that women can still menstruate when pregnant. She would know by now right? We are both still virgins by the way, getting ready to go to college. She thinks that I'm crazy and doesn't think there is any possibility. Any comments?
