My mom won't let me go on the pill: she says it makes kids go out and have Sex... my boyfriend and I have had sex before and yes she knows. My stepmom however wants me to go on cause she thinks "I'd rather you have safe sex then unsafe" (although my stepmom doesn't know about my boyfriend and I having done it before). Anyways we don't have sex anymore and I just want it for my cramps... however my mom won't let me go on it. I don't know what to do? And if I find a way to get some what kind should I get?
