What it is
It is more likely after a change of sexual partner, with an IUD, or with douching and perfumed products. About half of people with BV have no symptoms.
In pregnancy it can slightly increase the risk of complications, so it is worth mentioning to your midwife or doctor if you have symptoms.
Common signs
- A strong fishy smell, especially after sex
- Thin, white or grey discharge
- Usually no itching or soreness
How it is usually diagnosed
- Questions and examination
- A vaginal swab to check the pH and bacteria
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Swab results
- Treatments taken and when, to spot a pattern if it keeps returning
Questions to ask your doctor
- Should my partner be treated too?
- What can I do to stop it coming back?
- Is it a concern in my pregnancy?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- Fever with pelvic pain, or heavy bleeding in pregnancy
