This cervical mucus protects the sperm during its passage through the female reproductive tract until it reaches the female egg and gets fertilized. It also provides nutrition or nourishment to the sperm during its travel through the female reproductive tract.

Ovulation occurs 10 to 14 days just before the onset of your menses. Before the onset of menses, white creamy discharge is increased in quantities. It makes the vagina moist. During ovulation, the consistency of the vaginal discharge becomes like egg white.
