Insurance won’t cover my Birth Control and I urgently need it.

I recently I was referred to try this website called Nurx where it gives you birth control for free WITH insurance or $5 for your first pack. I heard really good views about it as well. The insurance i use Nurx doesn’t accept it and im kinda bum bc this is the only way i could receive BC without my mom knowing. She doesn’t want me on it. But i’m a sexually active teen so i think i should be on it. And i have no way to planned parenthood i don’t have a car rn so i’m out of options. I could pay $5 for the pack but my card and account is linked to my mom so she would find out. I really need help to pay for it since its only $5 anyone willing to help? Really trying to get on birth control before my boyfriend comes back in town! Thank you so much for the help if any!
