Jul,
I got this off the web. Hopefully it's useful.
Stages of Cervical Fluid: Post Menses
Stage 1: Lasting 2 - 3 days CM is Sticky or Gummy (S)
Stage 2: Lasting 2- 4 days: CM is Creamy, Milky, Lotion Like - Beginning of your fertile period (C)
Stage 3: Lasting 1-5 days: Egg white Cervical Fluid - At this time you are very fertile. (E)
Stage 4: Dry, Moist or Sticky (Infertile)
Peak fertile cervical mucus is thin and stretchy. After ovulation, progesterone abruptly suppresses the peak mucus and the mucus pattern continues with sticky mucus for a day or two, and then returns to dryness.
Egg White Cervical Fluid
How Long do you have it: Typically women in their mid twenties have it for approximately 5 days, by mid-thirties, only 1-2 days, but this is not the rule. Many women have several days of EWCM late into their thirties.
Look and Feel: The Cervical Mucus will look and have the consistency of egg whites. It is slippery to the touch and if pulled between the fingertips will stretch 1 - 10 inches.
Color: The color can be clear or iridescent and extremely wet. If your CM has an unusual odor, consult your physician, this may be a sign of infection. If your CM has the consistency of cottage cheese, this may be a sign of a yeast infection, also consult your physician.
There are natural ways to improve cervical mucus. Some women have have what is called Hostile Cervical Mucus.
After ovulation and under the effect of progesterone, the mucus becomes thick and sticky. Sperm cannot penetrate it. Once the sperm are in the mucus, they can stay there for a few days acting as a sperm reservoir. It can also be highly acidic and can kill the sperm.
If you are unable to naturally improve hostile cervical mucus, you can opt for Intra-Uterine-Insemination (IUI). The semen is injected into the uterus bypassing hostile cervical mucus.
