I have noticed a thick, white discharge from my vagina. I am not sexually active so I know it cannot be an STI. Is there something wrong with me?

Vaginal discharges are normal. You will have different vaginal discharges throughout your menstrual cycle.

Usually about half way through your cycle your vaginal mucus changes to a thinner texture that is more elastic and a clearer colour. This usually signifies when you are most fertile. It is totally normal.
