What is vaginal discharge?

The purpose of discharge is to keep the vagina clean and healthy. The secretion of it is usually one of the first signs of puberty and it continues till menopause.

Discharge is normally thick and creamy at the beginning of the cycle, when the hormonal system begins to prepare the egg and ovulation. During ovulation the discharge is normally quite clear. Just before the period starts the secretion of discharge is very minimal.
As long as the color of discharge is white, clear or light yellow and it doesn't smell bad, everything is fine :)
