could I be pregnant?

Yesterday me and my boyfriend were hanging out and things started to get a little.... messy. He started jerking off and he came. Then like 15 or 20 minutes later he fingered me with the same hand. Is it possible for me to get pregnant from that? He had cum on his hand but he wipped it off with napkins but could there still have been some on his hand? Or did it die? Please answer I'm kind of freaking out about it:
