Getting On Bc Without Parents Finding Out

So i’m still living with my parents and i’m still on their insurance, and i’ve recently become sexually active. We’ve been using condoms and we’ve been very careful about them and using them correctly, but since i have a normally irregular period, i am constantly worrying about being pregnant. I also know that a lot of women’s periods tend to act up after they first become sexually active, but i wanna get on bc to help further protect us. However, my parents wouldn’t approve and i’m not sure how to go about getting the pill or some form of bc without them knowing and without insurance, any advice?
