help!!! Idk if I'm pregnant

So me and my boyfriend were getting freaky. And I told him I didn't want him to put it in because I'm a virgin so he was just rubbing himself against me (with no condom). He didn't cum but there's a thing called pre cum I think I felt it on my fingers but t was like very little. Can I get pregnant if it was on the outside of the vagina. Can I be pregnant if I was not even like a drop of spit. Was it pre cum? Or like line he produces I'm scared and I'm 16
