Virginity and safe sex

Hi, so me and my boyfriend are both virgins and we are planning on having sex soon. We’ve been together for over a year and both feel confident and ready. He has condoms to use when we do have sex and stuff, but besides the condom we have no other form of birth control and i am terrified of getting pregnant. Is there anything else we can do to ensure I don’t get pregnant? Besides the condom? I’m probably overthinking and stuff but I wanna make sure we do everything possible to be safe.
