worried!!??

alright so I have major anxiety about everything but I just wanted to check, and eve seems to be the place to ask.

Yesterday my boyfriend and I had a bomb session, he came and we cleaned up with some Kleenex, pretty sure he went to the bathroom, went out and then came back home an hour later and we spooned. We started getting frisky again and he ended up teasing me and this lead to that. We didn’t have full on sex, but he didn’t have a condom on and I’m not on the pill. I’m worried about left over semen but from earlier should have dried, but still I’m super paranoid I could get pregnant. help me out fam what do I do.
