Should I talk to my mom about birth control...?

Taking birth control reduces size and severity of periods for most people. Also, if you find that your acne gets especially bad around or before your period, birth control can really help to reduce it. These are two very valid, very non-sexual needs you can use if you need to convince your parents to get you on birth control. Every drug has side effects, but with birth control they are usually small or unnoticeable for most people. My girlfriend takes it for both of the things you mentioned and it works really well for her.
