Am I still a virgin?

Yesterday me and my boyfriend decided to have sex and it was both of our first times. But we had trouble at first. He had trouble getting in (this is embarrassing for me btw) and I'm not sure if it was because I never done it before and was too tight or if we were just inexperienced. But i started bleeding and still am, like a period. I'm not sure what's going on, and I woke up feeling light headed and dizzy. I doubt I'm pregnant as we decided to give up. So can someone give me some advice?
