This condition is often treated with antibiotics. It's important for your future health that you not ignore it, and you are trying. I don't know what you are using, or have used. I am hoping you used it exactly as prescribed.
This site, and many others, give information about bacterial vaginosis, this is an excerpt from there, it lists two antibiotics recommended by the CDC:
"BV is treatable with antibiotics prescribed by a health care provider. Two different antibiotics are recommended as treatment for BV: metronidazole or clindamycin. Either can be used with non-pregnant or pregnant women, but the recommended dosages differ. Women with BV who are HIV-positive should receive the same treatment as those who are HIV-negative.
BV can recur after treatment."
If you have not used either antibiotic, perhaps you can ask for one. But as you can see, they say BV can come back even after treatment. There is a lot of information at that site and referrals to others. I hope it helps you.
I am sorry this is happening to you. Be sure to follow exactly the instructions for the medication given and use it for the full course, even if you feel better, keep taking it.
