I have BV and I am taking Metronide again after the first round did not clear up my BV. From other sources some say to try plain yogurt which has living cultures in it, by dipping the yogurt with a tampon and placing said tampon inside the vagina. Leaving it for up to 3 hours twice a day.

Do you think with both Metronide and Plain Yogurt at the same time it will clear up my BV?
