Bacterial vaginosis (BV) is the most common vaginal infection for women of childbearing age, states the Centers for Disease Control and Prevention (CDC). It occurs when the amount of harmful bacteria in the vagina increases, but the exact cause of why this harmful bacteria increases is unknown. Although bacterial vaginosis is common and can go away on its own, it can cause serious complications, especially in pregnant women. Therefore, although most women with BV will not show any symptoms at all, those women that do show signs of the infection should contact their doctors for treatment as soon as possible.
Abnormal Discharge
Abnormal vaginal discharge can occur with bacterial vaginosis. This discharge is usually white, yellow or gray in color and can be thin, watery or foamy, according to the National Women's Health Information Center.
Odor
The CDC states that some women have complained of a strong fish-like odor when bacterial vaginosis is present. This odor can be particularly strong after sexual intercourse.
Burning or Itching
Women with bacterial vaginosis can also experience a burning sensation when they urinate. The area outside the vagina and the vagina itself may also be itchy, sore or irritated. This area may also become red or swollen, warns the American Academy of Family Physicians.
