A 28-year-old nonsmoking woman presents to discuss birth control methods. She requests a contraceptive option that is not associated with weight gain. She and her husband agree that they desire no children for the next few years. Her periods are regular, but heavy and painful. She frequently stays home from work on the first day due to severe lower abdominal cramping and back pain. She changes her pad every 4 hours. This pattern of bleeding has been present since she was 15 years old. For a week before her period begins, she is uncharacteristically tearful, irritable, and depressed. These behavioral changes are beginning to affect her personal relationships. Her physical examination reveals blood pressure 110/75, BMI 22, and moderate acne on her face and neck. What recommendation would best address her mood, skin, and contraceptive needs?
