HELLLPPPP!!!!!

Hey Ladies. So my boyfriend and I had sex today and everything went ok. I was on top on him when he finished. We didn't stop right then because I did not finish. So we stayed in the same position and continued for probably around 5 minutes. I was just wondering if there was a possibility that his cum would have came out of the condom at all since it was in a vertical position. And if it did if it was close enough to get me pregnant. Thanks for listening and please enlighten me on this topic.
