My Family is too Scary...I Need Your Help 😩

I'm a teenager with severe anxiety over the thought of becoming pregnant. My family and I are very religious, I go to church every Sunday and my family is against birth control and any other sort of contraceptive. I have been happily together with my boyfriend for 2 years now, and it's been amazing. The only thing that seems to happen month after month ever since we hit about 1 year is that I get scared I'm pregnant. Some months I don't but honestly for the majority I do..it's horrible and taken such a toll on my mental health. I have talked to my mom/school councler before..but honestly month after month it seems to happen and nobody wants to hear it.😪 I have NEVER had VAGINAL SEX. EVER. I want to wait to have sex until marriage. But now here I am...scared again this month staying up each night having panic attacks wishing my period would come early. Just this last Friday it was my Ovulation Day I think..or at least the highest percentage of becoming pregnant day for me according to Glow. I told my boyfriend so that or 'goofing around' that night would be extra careful and we would make sure to really be cautious..but I knew that I wold still get scared. So here I am. 😔 I am really scared that while my boyfriend and I were in the middle of all this foreplay that he happened to have precum on his fingers and then finger me. While we were in his car I was giving him oral sex and he was playing/fingering my butt/vagina. He would and then masterbate and then go back to my vagina..ALL EJACULATION WAS NO WHERE NEAR MY VAGINA. Through this whole thing I actually did have pants on and he would just reach in and finger/fondle now and then. What are the chances of precum,if he even had any on his fingers, get into my vagina and get me pregnant?? I am so sick of doing this to myself.😣
