Birth control

So I’m 17 and I’ve been thinking on going on birth control since me and my boyfriend are sexually active. I’ve asked my mom about it but she told me if I didn’t want to get pregnant then don’t have sex at all (ok mom🙄) is there any way I could get birth control without them knowing from our insurance? And will it show if I use my health card? I turn 18 soon but I don’t really know if I wanna wait that long
