This is known as egg-white cervical fluid, and is the most fertile. When you see the stretchy, clear fluid, it s the best time to have intercourse. On the average, a woman will have a couple of days of this egg-white cervical fluid and then ovulate. There may also be some spotting around the time of ovulation. The spotting is a result in the sudden drop of estrogen just before the egg is released.
Some women do no't produce a lot of egg-white type cervical fluid.
In that case go by the wet feeling or sensation in the vagina. The peak fertile day is the last day of wet vaginal sensation or the presence of egg-white like cervical fluid. Be aware that semen can mask true cervical fluid. Be sure to mark on your chart when you have intercourse, to help in determining the type of cervical fluid you find. After ovulation, the cervical fluid will dry up or become creamy.
