What Causes bacterial vaginosis?
Normally, a lot of good, healthy bacteria live in the vagina along with a small amount of potentially harmful bacteria. But sometimes this balance can be upset by things like douching. That can lead a girl to develop bacterial vaginosis.
Although medical experts don't know for sure what causes BV, they do know that certain things can make the infection more likely, such as:
douching new sex partners or many different sex partners (male or female) cigarette smoking
You can't get BV from things like toilet seats, sheets and towels, or swimming pools.
How Do You Know If You Have It?
Many girls don't see any signs of BV. But those who do might notice:
an abnormal white or gray vaginal discharge that's thin, with a bad, fishy smell that's more noticeable during a girl's period or after sex pain while peeing itching in and around the vagina
It's normal to have vaginal discharge at different points during your menstrual cycle. But if you notice any discharge or other vaginal symptoms that don't seem normal, contact your doctor
Call your doctor or go to the emergency room and see what they say.
