Bacteria Vaginosis

Bacterial vaginosis (BV) is the most common vaginal infection in women ages 15-44. It happens when there is an imbalance between the "good" and "harmful" bacteria that are normally found in a woman's vagina. Many things can change the balance of bacteria, including:

Taking antibiotics
Douching
Using an intrauterine device (IUD)
Having unprotected sex with a new partner
Having many sexual partners
With BV, you may not have symptoms. You could have a thin white or gray vaginal discharge. There may be an odor, such as a strong fish-like odor, especially after sex.
