Can I be pregnant? Please help ASAP?

Ok so here we go. One day my bf n I were playing around; we were ontop of eachother. We were both wearing clothes, he had pjs on while I had panties on with sweatpants. I'm an irregular so I haven't gotten my period since November 09 , but I'm still a virgin. So now I'm afraid that I might be pregnant. I usually get alot of discharge, so in one part, he was ontop of me. His was rubbing against my vigina, it was on it, but we had clothes on. I felt myself getting wet. When I looked at my panties, there was alot of discharge. I never felt that his pants were wet. But maybe I didn't feel it and it went through my sweatpants. My question is, is it possible that he may have leaked & it went through my sweats n into my uterus. Please help
