BV isn’t actually a STD. But having sex can increase your chance of getting it. As well, BV increases your risk of getting HIV if you have unprotected sex with someone who’s HIV infected. This is why it's included in the STD section.
What are the signs that you've got bacterial vaginosis?
Most women with bacterial vaginosis, or BV, have no symptoms. This is because for most women, it's a harmless bacterial overgrowth. However, for some women, this overgrowth produces unpleasant symptoms.
Bacterial vaginosis symptoms can include: Creamy white or grey vaginal discharge
Strong vaginal odour sometimes smelling of rotten fish
Pain when you pee
Itching around the outside of the vagina
Redness and swelling of labia and the outside of the vagina

What happens if you do nothing about bacterial vaginosis? If you do nothing about bacterial vaginosis, in itself it shouldn’t usually cause you any serious health problems.
Untreated BV becomes a problem if you have unprotected sex with someone who’s HIV positive. It then increases your risk of getting HIV. And if you have unprotected sex with someone infected with genital herpes, gonorrhoea, or Chlamydia, having untreated BV increases your risk of getting these STDS too.
