My boyfriend and I started dating about a month ago, and before I met him I was still a virgin, and I'm 17 years old. We started having sex about 2 weeks ago. I bled the first few times we had sex, and I figured it was just my hymen, because it hurt really really bad when we first stated having sex, and it still does, so every time we do it, I have him finger me first to stretch it out a little. Just 3 days ago, on wednesday night, we had sex and the condom completely broke in half when he came. I can't remember exactly when, but soon after that, I started bleeding, as if I was on my period, and I already had my period last week. I am taking birth control, but I don't think it's working at it's fullest effectiveness, because I have been taking it at different times, and sometimes skipping a night because I forget. Yesterday I got bad somache aches and cramps, and I was still bleeding like I was on my period. Today I am still bleeding, and I notice that my vagina itches. I don't know what to do, if I should continue taking the BC, or have sex until I know whats going on. Is there somehong wrong with me? Am I pregnant? Do I have an STD or STI? We are both really scared and need answers. Please help me.
