Pregnancy

Sooo I’m a teen and I have major anxiety abt getting pregnant. I’m on the BC pill that I take perfectly so that means it’s 99.7% effective I think. Also my bf never cums in me ever. He pulls out way before he cums and we do oral. How do u keep yourself relaxed when coming close to ur period? I always get so nervous thinking I’m pregnant and then my period comes and I’m like y did I stress so bad?? What r good ways to stay calm? Advice? Also for the women who r gonna tell me to use condoms Ik😖 sometimes my bf and I get caught up in the moment and we just enjoy raw a lot more.
