I agree with Perna and her funny definition of good and bad little buggers lol. Antibiotics can cause Yeast Infections and then you'd need some anti-yeast treatment. Have your doctor cultured the discharge - its important to know what beast you're fighting. Have you have a pap test - cervical changes can cause odor...so can Pelvic Inflammatory Disease. Do you use tampons - it has happened where one gets lost - sorry if this is TMI but it happens. Until this goes away, use a condom. Stay away from douches, since this area doesn't need harsh cleansing. Eat all natural yogurt.
Buy some Oregano Oil and take the drops by mouth - this fights bacteria etc in your body. Its also good to take a Vitamin C - I take a special one called Ester C and this is easier on the stomach and helps balance the PH of the body....its more expensive ($15). There is this cleansing device that uses just water that was on the Doctors Show and I'll leave you a link - called Water Works. When you're home alone, wear lose clothing without underwear - the idea is to let that area have air and be dry. Don't wear G Strings - bacteria can literally migrate to that area. When you do wear underwear, make sure its cotton in that area. The main thing is - you want to know what's the cause - is it yeast, bacterial, or something else. Also no harsh soaps. I hope you find a solution.
