Paranoid I’ll get pregnant again lol

Am

So, my fiancé is planning on getting a vasectomy. In the mean time I’m on the pill and I take it same time every night. But I’m still paranoid that I will get pregnant again if we have sex 🤷‍♀️ we had sex a couple weeks after I started the pill and I’m paranoid that it wasn’t enough time to wait before we did. It took me over a year to get pregnant so it’s not realistic to be this paranoid...anyone else???
