How to ask my mom to get on the pill

I’m not sexually active yet, but I want to be prepared for anything, you never know...🤷🏾‍♀️ But I don’t know how to ask my mom to get birth control. We don’t actually talk about stuff like that usually and I know the first thing she’s going to think is that I’m having sex. Plus we’re kinda a religious family, so I really don’t know what to do 😭
