How do i get on bc without my parents knowing

I’ve had a pregnancy scare recently and i just don’t want to be scared anymore. I want to get on birth control and use a condom so ik that i won’t get pregnant. But i’m 17 so my parents aren’t for any of that. they don’t want me doing it at all because anything can happen and they think i’m too young. so i need to figure out how to get on bc without them knowing and keeping them from knowing
