Thanks for asking at Healthcare Magic. I read your question and I understand your concern. Brownish vaginal discharge is generally benign but when it s foul smelling then it implies bacterial infections. Bacterial vaginosis is usually white discharge. Needs PV examination by Gynecologist. All that you need is to do Microscopy of vaginal discharge. In order to prevent repeated infections, you have to follow the following steps. 1. Wipe yourself while attending bath room from front to back to avoid soiling by stool. 2. Avoid spermicide 3. Wash daily with mild warm water in case of bacterial vaginosis you have apply metronidazole gel twice weekly for 4-6 months after antibiotic therapy.
