I had sex with my boyfriend without a condom and I trusted him enough that he knows when to take it out before he comes. So anyway we did it and now he is telling me that he busted inside of me. But idk if I'll be pregnant or not because I was on my period and I've been on it for four days when we had sex. Please try to help me out with this please. Idk what to do. He said that he doesn't want me to lose it but I don't know if I want to keep it.
