Many women find the cervical mucus check to be the best way to predict ovulation. In general, as the day of ovulation approaches in your cycle, your vaginal and cervical mucus should increase (i.e. become more moist) and the consistency should become slippery and clear (such as that of egg whites).
This type of egg white discharge helps sperm to move faster and to survive longer within the female’s body giving the best chance for fertilization of the egg.
