so I'm only 16 and I want to be put on birth control. I've had sex with this boy multiple times but we only use condoms and I need to be on it I just don't know how to tell my mom that I'm having sex with an 18 year old. plus we're not even dating its like a FWB, so I don't know what to do because I don't want to end up pregnant, but I also don't want to tell her. my friends tell me to tell her it's for my period, but I think she'll know cause it'll be random. what do I do
