You do know that birth control pills are used for problems apart from reproduction, right?

"Adolescent girls and young women are often prescribed birth control pills for irregular or absent menstrual periods, menstrual cramps, acne, PMS, endometriosis, Primary Ovarian Insufficiency (POI) and for Polycystic Ovary Syndrome (PCOS). Girls who are diagnosed with PCOS are often prescribed oral contraceptives to lower their hormone levels and regulate their menstrual periods."
