Help??

Ok so, my period is about 8 days late. I know that there’s very very little chance of me being pregnant because, while my boyfriend and I have done stuff, he always dry humps me through my leggings and underwear while he has on sweats and underwear too, and whenever I jerk him off/blow him I ALWAYS wash my hands 2-3 times right afterwards and try to minimize contact with my vagina for like 2 days (just to make me feel better). But, my period is still late and they’re typically pretty regular going from about 29-35ish days. Last month though my period was super light, still lasted a week though, but my cycle was only 24 days long. Now this month, we’re going on day 40. I had a pretty rough month in January and blamed the earliness on that. This month all I had was my auditions for college, but it still stressed me a bit. I’m just wondering 1 there’s no way I’m pregnant right? And 2 should I see a doctor if my period still isn’t here within the next week? I’ve been wanting to go on bc for a while but my mom won’t let me because she’s convinced I just want to have sex even though I just wanna regulate my period.

For reference I’m 17 and my family is pretty religious and while I know I really can’t get pregnant from anything we’ve done, I get myself all worked up over it for no reason when something’s off. Hearing someone else tell me I’m ok helps me calm down, please don’t be mean I just want to hear it from someone else and I’ve been educating myself on everything the best I can.
