Introduction: 

This case provides an opportunity for you to delve into diagnosing and managing persistent vaginal discharge while considering contraceptive methods for a sexually active young female. This case aims to reinforce your understanding of diagnosing, managing, and preventing sexually transmitted infections, as well as providing comprehensive contraceptive counseling.

Case Profile: 

Ms. Smith, a 21-year-old college student, visits the clinic due to a persistent vaginal discharge and to discuss birth control options. She and her boyfriend have been sexually active for about a year. Their main contraceptive method is condoms, but they are not always consistently used. She seeks a method with a lower failure rate. She maintains regular menstrual cycles and has no significant past medical or gynecological history. She describes her vaginal discharge as greenish-yellow and reports mild vulvar itching. Upon physical exam, she has normal external female genitalia without any lesions or erythema but does have a greenish discharge present on the vaginal walls and pooling in the posterior fornix. Her cervix appears normal but shows friability with light manipulation. Her bimanual examination is unremarkable.
