Condom problems

So my boyfriend HATES wearing condoms. We have already had 3 pregnancy scares he said he pulls out every time and I swallow after we have sex but it causes me so much stress to have sex with him. It’s almost like I can’t enjoy it anymore without being scared of getting pregnant. Keep in mind:: I’m only 16 and my boyfriend and I have only been together for 9 months. I can’t take any birth control because my mom believes in only consuming things that are “organic” and “all natural” and if my parents found out I was having sex I would be in so much trouble.

Please help!!!
