about to get married & im a virgin

Hey ladies! So I'm about to get married, and I'm actually a virgin. On the honeymoon, I want my husband and I to experience sex together without any condoms and I want him to reach his climax inside of me. I've been on birth control for over 5 years due to terrible menstrual cycles, so I know I should be good to go! But I still fear that I'll get pregnant, probably because I've never had sex before. Can any of you please tell me your experience with being on the pill for a while and allowing you to have regular sex freely? Thanks!
