So my girlfriend is 19 and I am 21. She is not on birth control and we just started having sex regularly. Well we had sex the other day and I was doing her pretty hard cause she likes it and later she said she was bleeding. I was told I might have hit her uteris or something that might be why she is bleeding. Or I popped her cherry. Anyway. She said that her boobs were kind of sore and she felt bloaded and that she might be on her period 2 weeks early. Now I have heard that if you have your period that you are not pregnant but it was just worrying me that she might be and I so hope not. I have been pulling out with a condom every time I have came except for twice and both times the condom wasn't broken or anything. So, if she is on her period please tell me that means she is not pregnant. She just told me today that its spotting and its lasted about 3 days. She also said her back and stomach kind of hurts. I honestly don't know how she could be pregnant is she is because I have used a condom every time and pulled out except for twice but the condoms aren't broken cause I checked. Please help Thanks for the help everyone. I really appreciate it.
