Teen pregnancy ?

My boyfriend and I have been having sexual for 3 years and I am 16 and he is 17. We really don’t want a kid right now, and I know we shouldn’t be having sex. We have never had unprotected sex. And my only protection is a condom. I cannot get on birth control because my parents are against it. I am afraid of pregnancy at this moment because we had sex 3-4 before my ovulation date (i had the cm that was stretchy and slimy). We used a condom and he pulled out long before he came. I’m scared of pre cum maybe being on the outside of condom from my hands maybe. Before we had sex I gave him a handjob but he only pre came the whole time, and then i wiped my hands and he wiped himself off. I’m just kinda freaking out. My period is due in 2 weeks and we had sex 8 days ago. Also, I was on the last day of my period when we had sex. Should I be fine?
