Fear of becoming pregnant again?

I’m so terrified of getting pregnant again. It’s like to the point I feel like I can’t even enjoy myself when hubby and I do the deed. I’m on the pill and we even wear condoms every time, but I can’t like shake the thoughts of if I were to get pregnant again... I just want to enjoy my sex life again... is anyone else feeling like this? I never had this anxiety about this with my first baby. (But I have also been diagnosed with PPD with this baby #2)
