Helppp so scared

Recently I have been experiencing pink discharge after sex. I experience no pain during sex and I’m usually well lubricated. I’m just scared bc my partner and I have unprotected sex all the time but I am very diligent and take my birth control on time. He thinks it could be pregnancy. I looked it up and think it’s polyps. Can someone help me ease my worrying because I highly doubt it’s pregnancy bc my BC pill stops ovulation.
