Don't judge me but I would like to learn about what does and does not get you pregnant

Alright so I have researched and researched my ass off but my worrying still hasn't gone away. I'm working on getting a therapist or counseling for this but for now I would just like some closure. I want to know that the things that I do can't get me pregnant. I am on the combined pill so I don't know why I am worrying so much. Basically I have never had sex and quite frankly I am scared of it, but I have given my boyfriend a blow job and hand job (to which he has cum on my hand but I wipe it off immediately) and we have 69ed but nothing gets near my vagina,i make sure of it. Also sometimes when I given him a hand job later on in the night I will pleasure myself but I wait at least an hour. Usually more than that to be honest. He also eats me out and rubs my clit. He has tried a few times to finger me but I ask him to stop after a few seconds because it hurts. Could any of this get me pregnant on the pill?? Also please no hate comments, I know that I should know these things but I never had a great education, I spent most of it trying to stay out of the way of bullies. Plus I was never good at science, especially the human functions
