Okay...My girlfriend had her period a couple days before we had intercourse for the 1st time with a condom and I pulled out just to be safe(it was about 3 minutes just to see wut sex was like)....And then she had her period again earlier than expected way earlier! And it was very light like almost nothing for 14 days now and its getting a little darker...She is on birth control, but she forgets a lot so she will take like 3 a day cause she missed or whatever....Is she pregnant??
