scared

so, i’m fairly young. (under 18) and my boyfriend and i have been together for a longggg time. i lnow it’s not smart but for spme reason the condoms hurt me so bad. so we go raw, but ONLY if my ovulation is low. the day we did it, my risk of pregnancy was 3%, and he didn’t cum in me. we stopped 5 mins before he came and he came to me giving him head. my period is 2 days late, were super stressed. should i be worried?
