How should i tell mymom

I think my mom saw my birth control and some condoms in my wallet but hasn’t said anything and I’m kind of tired of hiding it. How should I bring it up w her? She’s very religious but also kind of weirdly understanding. Like she used to tell me you can only use tampons after you’ve had sex and got mad when I asked about them but when I told her i started using them she was calm and just shared w me that when she tried them she didn’t like them and preferred pads. I’ve brought of getting on the pill for cramps a while ago in front of my doctor, but when we got home she got mad at me and said no but I told her that there was ways I could get it with out her and she didn’t say anything. Basically I don’t know how she’s gonna react. Help pls
