Common Clinical Scenario: A 32-year-old woman who recently moved to your city presents for her first prenatal visit with you at 26 weeks of pregnancy. Her only prior pregnancy resulted in a preterm delivery at 32 weeks. No underlying cause for the preterm labor was found. She is otherwise healthy, and her prenatal care to date has been unremarkable. Cervical length has been checked and is normal. Examination reveals a relatively asymptomatic vaginal discharge which screens positive for bacterial vaginosis. She wants to know if she should be treated. What do you advise?
