<human>: Condense the text into a few key points

Hello!
I've been sexually active with my SO since April. He's my first and I've never had any sexual experience before dating him. We took a little break from May - July because we didn't see each other over summer. I don't know if this is normal, but sometimes I get excessively paranoid that I'm pregnant. I'm on the combo birth control pills and he uses condoms. There was one occasion where we were both really horny but we had no condoms, so he penetrated me but withdrew way before ejaculating. However I got really freaked out after that and we both agreed that it simply wasn't good for my anxiety. Because of my anxiety, I'm usually very good at taking the pill. I usually take it on time, or at most within a 3 hour window. There was one time where I fell asleep and forgot to take it, but I took it 9 hours later.
Heck, I'm still really paranoid now that I'm pregnant now even after getting all of my withdrawal bleeds on time. This is kind of affecting our sex life because I've become slightly more hesitant during sex, and I also initiate a lot less. How can I overcome my excessive fear? Is this paranoia even normal?
<bot>: Excessive paranoia about pregnancy possibly ruining sex life. Convinced myself I am pregnant even after very many months of timely withdrawal bleeding.
