Bacterial Vaginosis: Symptoms...

The most common symptom of BV is an abnormal vaginal discharge (especially after sex) with an unpleasant fishy smell.

There is rarely itching.Nearly half of all women with BV don't notice any symptoms. By contrast, a 'normal' discharge will be odourless and will vary in consistency and amount with your menstrual cycle - a normal discharge is at its clearest about 2 weeks before your period starts.
