Vag Odor/Discharge: If you have any new odor or discharge-->vaginal exam by your OB/GYN. BV and yeast infections often coexist, and odor can have other contributing factors such as hygiene, sexual activity. You should also have a pap smear and maybe some colposcopy or a hysteroscopy by your OB/GYN to evaluate and examine anything in your uterus that may be contributing. A culture may be helpful.
