The Complications
All women are at risk of getting BV, but your chances are increased if you are sexually active, have an IUD (contraception device), are a smoker and frequently douche. There is a small chance of complications, such as premature birth or miscarriage, if you develop BV while you are pregnant.
BV can also increase your chance of getting pelvic inflammatory disease (PID), which is a serious pelvic infection that can cause fertility problems.
Symptoms include a burning sensation when you urinate, thin white, gray or green discharge, pain, itching or burning in the vagina or an unusual vaginal discharge that has a strong fishy smell, particularly after sex.
