I need some advice

So, I’m scared of sex because I’m scared to get pregnant. I just found this app and these discussion boards. I lost my virginity when I was 18 but ultimately it didn’t work out because I didn’t like always being scared to get pregnant so we quit having sex and he broke up with me. Basically every relationship has failed because of this. I recently started dating someone and I’ve never felt this way about someone and can really see this guy in my future for a long time. We’ve had sex a few times but I still get lots of anxiety about getting pregnant. We’ve talked about it a lot and it’s not a huge problem right now but I know eventually it will. I’m doing everything possible not to get pregnant (birth control, condoms, and pull out) but like I said I still get lots of anxiety. How do you get over this feeling? I don’t know how to stop stressing. I haven’t had a ton of sex for this reason. Is it something that will just have to come with time?
