Okay so my girlfriend starting taking the pill November 10th. Her next period is scheduled to start december 1st which means she was ovulating right around the 15th of this month. We did have sex that day, i went unprotected for a little but I put on a condom and finished in the condom. There were no breaks in the condom. As of late my girlfriends boobs have grown and she says they hurt and she has been nauseous. Is it from the birth control or could she be pregnant. I have ejaculate inside of her, always in a condom, but im a hypochondriac and I know pre cum can contain sperm. Please someone help im flipping out
