Birth control

How likely is it to get pregnant while I’m on birth control and my boyfriend always pulls out. We don’t use condoms but he pulls out Im just worried about precum. I know it can get me pregnant I’m just worried because I passed out the other day when we were in a barn getting hay. My boyfriend said I was wobbly and saying I was gonna puke then he told me to sit down and I passed out on the hay bails twice then got up and wouldn’t sit back down then I just collapsed.. I don’t remember it. My vision was blurry but anyways so I’ve never passed out before it was hot out though. It could have been from the heat. But I’ve also had plenty of pain around my pelvic area and my periods not for awhile yet. I’m just nervous someone help how good is the pill?😩 I can’t be pregnant Im way to young I still live with my parents they don’t even know I’m sexually active and my boyfriend is just ab to be 18 so that would be major legal issues. I need to take a test I’m just worried. I don’t think I could possibly be pregnant he doesn’t even cum in me and I’m on the pill but has anyone gotten pregnant with both methods ?
