Ahh, venting a lil

So you guys, my bf and I had unprotected sex last night which was in my fertile period 4 days before ovulation. We have had sex plenty of times but this time after we got done I just had this feeling that I would conceive. I’ve never felt like this before but has anyone ever felt like this? He never nutted in me but I aware that precum can get you pregnant. I’m 24 and he’s 27. My dad is a Pastor as well so I’m afraid of the outcome that would happen if I did fall pregnant.... any advice would help.
