I might've lost my v-card.

Well I finally did it, but the thing is, he didn't fully penetrate me, but when he tried, it hurt that I had to tell him to stop. When I got home, there was some blood, but I imagine it's from him trying to go inside.  I'm not too worried about the blood, but I am worried I might be pregnant. He finished on my stomach and there was no cum inside me. But being that it's my first time, I feel like he should've worn a condom. And I fear that my worst fears could come true. I was drunk and so was he. But I also feel like I was responsible enough to tell him that it hurt, and to not come inside me. I don't know what to do, I'm confused and I have all these new emotions to deal with, but that is my main concern. We didn't freak out when we were done, but now I am. So... Yeah.
