Is pregnancy a possibility?

So, my bae and I just had some STELLAR sex, and we were chatting after he came in me (well, technically in the condom in me, but my point still stands) and when he went to pull out he had gone soft again and the condom slipped off. Some of his semen leaked out of the condom, but it didn't go in my vagina, just sorta dribbled down onto the bed.
