Discharge is a fluid that leaves the woman’s vagina. This is totally normal. When girls enter puberty a secretion is produced in the cervix and in the mucous membrane of the vagina. This discharge is usually pale in colour and almost odourless. The amount of discharge can vary from woman to woman, but it is usually small amounts. The discharge can change appearance and thickness around the time of ovulation, or when the woman starts to use combined contraceptive pills or has intercourse. The discharge helps protect the mucous membrane of the vagina. If there is a notable change in colour or if it starts to smell strongly, this may be a sign of vaginitis. In this case a doctor should be consulted.
