A 26-year-old woman presents with new vaginal discharge. She reports the onset of a thin, whitish discharge with an unpleasant odor that was most prominent during her recent menses one week ago. She is sexually active only with cisgender women and reports having two sex partners during the past 6 months. She denies fevers, chills, pain during sex, pain with urination, or vaginal itching. On pelvic examination, there is no evidence of vulvovaginal inflammation, but there is a thin, white, homogeneous, “fishy smelling” discharge.
