Pregnancy Scare

Okay so. My boyfriend and i were fooling around and i had my pants down and so did he and he was rubbing his dick against my vagina but he did not enter, he was just teasing me. Is there a possibility i could get pregnant? He didnt cum, but maybe his precum might have did something? Once again he didnt go in but he was near my entrance.  He also fingered me after if that has anything to do with it.
