I need help ladies!!!

So this past Saturday I had unprotected sex. (He’s clean) I’m not on birth control but he pulled out. I’m still super paranoid though because I was ovulating at the time which I wasn’t aware of :/ or else I probably wouldn’t have done it. I also heard that you can get pregnant from pre-cum idk if that’s true or very likely?

I don’t get my period for a couple weeks and I’m just super paranoid. Someone tell me if I should be scared or if I’m fine😩
