New To Sex

So I’m 16. Im on BC and my bf and I use a condom but I can’t help but get paranoid about pregnancy. I know I’m using protection but the thought is always in the back of my mind.

Also my bf and I just started having sex cause we were waiting for my BC to start working. (My doc said it would take 1-2 months to work and it’s been a month and a half)

Anyways I was looking for advice on how to relax and not always get so nervous about pregnancy.
