The investigators are trying a combination vaginal product of higher dose metronidazole combined with miconazole to see if it is effective in treating vaginal trichomonas.

This purpose of this study will be to conduct a double-blind, randomized, controlled clinical trial to determine the association between intravaginal high dose metronidazole (750mg), intravaginal high dose metronidazole combined with an antifungal agent(750mg metronidazole + 200mg miconazole) and low dose (37.5mg) intravaginal metronidazole, with the rate of persistent bacterial vaginosis.
