Well about 4 days ago me and my boyfriend had sex. I am on birth control and we weren't planning on doing anything so he didn't have a condom. We did it twice around a 2-3 hour period time and it was kind of pain full when we started but and he had trouble going in both times. And now yesterday I started bleeding but it wasn't heavy so I went to bed and put a pad and now I have cramps. Also when I pee I doesn't burn, I just don't know if I should be worried or not. Please help.!
