I need birth control but my parents are against and i can't talk to my doctor i am 18 i have painful periods and i'm about to be sexually active i am way to busy to go to a clinic what do i do ?

You are an adult: and can talk to a doctor and make the decision to go on birth control for your periods, Call your doctor and make an appointment.

Adult decisions: At 18, you are an able adult, and can make your own health decisions. Part of adulthood is managing your time and health. Unless you are prepared to take care of a potential pregnancy, you will need to make the time to make a proper appointment to discuss your birth control options with a gynecologist or family practitioner.
