You have a vaginal infection called bacterial vaginosis (BV). Both good and bad bacteria are present in a healthy vagina. BV occurs when these bacteria get out of balance. The number of bad bacteria increase. And the number of good bacteria decrease. BV is linked with sexual activity, but it's not a sexually transmitted infection (STI).
BV may or may not cause symptoms. If symptoms do occur, they can include:
-
Thin, gray, milky-white, or sometimes green discharge
-
Unpleasant odor or “fishy” smell
-
Itching, burning, or pain in or around the vagina
It's not known what causes BV, but certain factors can make the problem more likely. These can include:
-
Douching
-
Spermicides
-
Use of antibiotics
-
Change in hormone levels with pregnancy, breastfeeding, or menopause
-
Having sex with a new partner
-
Having sex with more than one partner
BV will sometimes go away on its own. But treatment is often advised. This is because untreated BV can raise the risk of more serious health problems, such as:
-
Pelvic inflammatory disease (PID)
-
Preterm delivery (giving birth to a baby early if you’re pregnant)
-
HIV and some other sexually transmitted infections (STIs)
-
Infection after surgery on the reproductive organs
Home care

BV is most often treated with medicines called antibiotics. These may be given as pills or as a vaginal cream. If antibiotics are prescribed, be sure to use them exactly as directed. And complete all of the medicine, even if your symptoms go away.

-
If you have sex with a female partner, ask your healthcare provider if she should also be treated.
