Condom slipped off. TMI! !!!

Madisson
So my boyfriend and I were pretty drunk things got hot and heavy. Well after he finished, he rolled off and the condom was still inside of me. I mean the base was still sticking out and we got it out pretty quick but he isn't sure he came in the condom. There was a very small amount in the condom. Should I be worried about pregnancy? We have already had one scare almost year ago and he freaked out and had a panic attack several times. Is there any chance I could be pregnant?
