I've been having sex for about a year now, and the guy I had sex with always pulled out. well last time we had sex, he pulled out (but I think it was a little too late) and I've been having these like cramps, but I missed a whole month for my period, and this month I had some blood loss, but it was only for like a few hours and it wasn't too heavy ? So I don't know if that means I'm pregnant and my body is still trying to have a period ? Or what? Please help. Because I'm worried, and I don't wanna ask my mom because I'm only 16...
