Hello doctor Okay, soooo me and my girlfriend had sex, she is young so am i, I wore a condom, she isn t on birth control.. She is late on her period, started craving pickles and penutbutter tonight, its ben a week since we had sex.. She had 1 big bleed, and then a light bleed the rest of the day, ON THE day she was supposed to be on her period. Do you think she could be pregnant or is this just like a late period induced by first time sex??
