A milky white discharge is usually normal. It represents cervical and vaginal secretions that contain old vaginal wall cells (epithelium). As long as there is no vulvar burning/itching, this does not represent a symptomatic yeast infection. The secretion of vaginal discharge which flows out of the vagina every day helps to maintain your vagina healthy and clean Vaginal discharge varies in its nature and consistency from one person to another and even for one person throughout the menstrual cycle. Commonly the discharge is grayish white or clear. The cells come from the vaginal lining and fluid from the vagina and the cervix. It often gets thin (non clumpy) at mid cycle of the menses because the cervical mucous is thin and copious if ovulation has taken place that cycle. In the 2nd half of the cycle it becomes thickened and sometimes clumpy under the effect of progesterone. These are all normal mechanisms to help a woman become pregnant at the mid cycle time of ovulation and then "block" the cervix in the 2nd half of the cycle so that if a pregnancy occurs there won't be any ascending infection.
