Help!!

I know that this is probably a stupid concern, but I need to ask to help calm myself down.

So, on Sep 2nd, my boyfriend and I did each other. We didn’t have sex and he didn’t even finger me, and I wouldn’t be concerned if I had been wearing shorts, but I just had a dress on and pretty thin underwear. I basically dry-humped him through a blanket, which I know is pretty safe since he didn’t cum. After I blew him/gave him a hand job, he came into his stomach and I left to wash my hands. Once I got back, I laid down on top of him and my lady parts weren’t over his stomach or penis but they were over his thighs pretty close to his penis, and he had wiped off his stomach with his shirt and then left his shirt off to dry so his stomach was pretty dry. I know there probably isn’t, but is there any way that I could’ve become pregnant from this? I think I ovulated on the 7th so my period is due in like three days, but still. My bbt hasn’t been as high po as normal, so I’m just worried. It also hasn’t dropped yet either. I am getting all of my normal PMS symptoms, but my boobs have been a little more sore than normal, but not anything crazy. And I have no symptoms of pregnancy other than that

(Before anyone bullies me I’m only 17 and I’m trying to educate myself on what can and can’t get me pregnant but I couldn’t find anything online about this scenario so please just help me out I’m from a very religious family so I have no clue what I’d do if I got pregnant)
