Odor before and after period. no std or bv. no yeast infection. dr said ph is off balance. affecting sex life. yogurt not helping. what can i do?

Bacterial vaginosis: Tallk to your doctor about rechecking for bacterial vaginosis, or get a second opinion. BV is by far the most common cause of both vaginal odor and "pH off balance". Yogurt never helps it. Trichomonas also is a possibility, and is missed over half the time by looking for it under a microscope; ask for the newer DNA test. Keep working on it -- this problem can be solved and effectively treated.
