If you find a “bleach” patch on your underwear, here’s what it means

Dr. Vanessa MacKay, with the Royal College of Obstetricians and Gynaecologists, explains: “The vagina has a self-cleaning mechanism through natural secretions. It contains beneficial bacteria that serve to protect it.”

As per the National Institutes of Health, the usual vaginal pH ranges between 3.8 and 5.0, making it moderately acidic in relation to the naturally neutral pH level of 7.

Dr. MacKay adds that it’s perfectly normal and healthy for women to have clear or white discharge from their vagina, while disturbing the natural balance can lead to infections.
