How do I tell my religious mother I want to get on birth control?

My mother knows I’m sexually active, and it’s hard to get condoms sometimes and the condom has broken so many times that I can’t even trust them anymore. My mother found out I’m sexually active and she lost her shit and told me to never have it again. Obviously I didn’t listen. Anyways, I want to get on birth control but she’s going to know it’s gonna be for sex. My mother is one of the most strictest and religious mothers on the planet who believes birth control is solely for denying the woman a chance at pregnancy which in her mind is soooo bad. So please, anyone. Help me.
