Depression during Pregnancy

A 24-year-old married woman presents with a 1-month history of diminished concentration and interest, insomnia, fatigue, tearfulness, and depressed mood. She is 10 weeks pregnant, stopped working 3 weeks ago, and mostly stays in bed. Two years ago, she was successfully treated briefly with sertraline at a daily dose of 50 mg for depression after a suicide attempt. She reports that she wants to continue the pregnancy and says that she does not feel suicidal. What would you advise?
