Anxiety about sex

Does anyone know how to help pregnancy anxiety when having sex? I’m always safe ( I’m on the pill and use a condom) I know how sex works and I logically know I’m overreacting but I have bad anxiety and was wondering if anyone has dealt with this and how they overcame is because I’d like to not be stressed about being pregnant every time I have sex. Update: I get sick a lot and always think I’m pregnant bc of it I take so many tests it’s a problem but I think I’ll get over it eventually 😂
