My girlfriend and I have always used condoms when having sex and I've always pulled out before with the condom on. And last week while we were having sex she started to bleed. She thought it was her period so she put in a tampon and said there was a lot of bleeding and she was cramping hard the whole rest of the day and having regular period syndromes. But the next day she called me saying it wasn't her period or if it was it's gone. She's trying to get on birth control and said that the doctor gave her a pill to make her period come early. But that was a month ago and she already had her period and so she's waiting on this month to start so she can start using birth control because she missed the doctor last month. What does this mean?!
