I'm 15 years old and I am sometimes sexually active and my mom doesn't and can't know. I want to get on birth control but my mom is Catholic and that's against our religion so I'm all the positive that she won't let me. I don't only want to get birth control because I'm sexually active but also so we can regulate my period. Could anyone give me advice on how to talk her into letting me get it??? or is there a way I could get it and not let her find out about it?
