We had unprotected sex a few days before she was suppose to start her period, I didn't ejaculating or even come close to ejaculating, but I don't know about pre-cum either. I got her a morning after pill just in case and she did take it. She's very stressed between school an this. The pill said 7/8 women will not become pregnant. She's a week late on her period. Should I be worried? Please help me.
