Okay, recap from a previous post. I messed around with this girl and she might have been exposed to some precum inside her vagina. So she took the Emergency Contraception Pill. Now I've heard many different things. People have said that periods come within a week and some poeple have said her period would come like normal. She took Plan-B and she told me her period came today, 5 days after she took the pill. I have no proof that it did except her word, so can this happen? Can her period really have came this soon? Oh yeah, she told me she had her period last week too before we messed around, so she was on a new menstrual cycle. Okay, next question. We messed around Sunday and she took the pill that day. I know sperm CAN live up to 7 days inside a woman's vagina, so even though she had/began her period today(Friday), does that mean she could still become pregnant?
