Cervical mucus also known as cervical fluid is a natural secretion of the cervical glands designed to moisten and protect the cervix. We are hesitant to become intimate with the less appealing parts of natural bodily functions, but changes in cervical mucus can be one of the greatest clues to determining when ovulation is about to occur.

Cervical Mucus Of The Menstrual Cycle

Prior to ovulation, during non-fertile periods, the woman will experience a dryness (or lack of cervical mucus). Gradually, as the woman approaches ovulation, the mucus will increase, though the consistency will be “sticky” and the color will be white, yellow, or cloudy in nature.

During the peak of fertility, the opening of the cervix is open, with clear, stretchy mucus present. The cervical mucus looks wet; it is clear in color, rather than the cloudy or whitish color when peak fertility was still approaching. There will be an increase in cervical mucus at ovulation, as well as a change in texture – the mucus becoming more pliable, “stretchable”, and slippery. The last day on which fertile Egg White Consistency Cervical Mucusis observed is considered your day of “peak fertility”.

Four basic changes of cervical mucus in the menstrual cycle

  1. There will be small or absence of cervical mucus in the first few days following your menstruation. The external genitals dry. Less amount of cervical mucus is an indication that pregnancy is not possible at this time.
  2. Early cervical mucus begins just prior to ovulation. It is thick mucus that is sticky, white or creamy in color. If to perform finger testing, the mucus will break easily when you pull your fingers apart. There is a chance that you could get pregnant at this time.
  3. The cervix mucus will begin to look cloudy and will increase in volume. The cervical mucus will be more stretchable in a finger test, but will still split before your thumb and forefinger are stretched completely apart. There is a chance for conception to occur at this point.
  4. Highly fertile cervical mucus occurs at ovulation. It is thin, stretchy and clear or pale white with resemblance of egg whites. The volume of the mucous will continue to rise until ovulation reaches its climax and the chances of conception are at their highest. It is the most stretchy mucous and can be stretched several inches between the thumb and forefinger before it splits. Unlike the other stages of mucus, the egg white mucus at the time of ovulation provides an optimal environment for sperm to survive.

How To Check Cervical Mucus?

You can choose from the 3 ways to perform this: Use of a toilet paper or your fingers across the opening of your vagina, wearing a panty liner or inserting your finger into your vagina.

Be sure to wash your hands thoroughly with an anti-bacterial soap prior to performing this.Find a comfortable position, either by sitting on the toilet, squatting, or standing up and putting one leg up on the bathtub edge or toilet seat.After washing your hands, or if you prefer, toilet paper, you can examine your cervical fluid. You can check your cervical mucus by wiping your vaginal area with a tissue. Observe the tissue. Close the tissue around the cervical mucus and open it. You can also insert two fingers into the vaginal cavity and pull the mucus from the cervix.

In addition to this method, there are other effective ways to help predict ovulation such as:

Other Things To Consider – When Checking CM

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. There are incidences that women have several days of egg-white consistency cervical mucus 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.

The color can be clear or shiny and extremely wet. If your CM has an odd smell, consult your physician, this may be a sign of infection. If your CM has a cheese-like consistency, this may be a sign of a yeast infection, also consult your doctor.


  • Don’t perform the cervical mucus test during or right after sex, or when you’re feeling sexually aroused.
  • If you have trouble finding anything, checking your cervical mucus after a bowel movement may be easier. (Don’t forget to wash your hands well.)
  • If you have polycystic ovary syndrome, predicting ovulation by tracking cervical mucus might not work well for you. Taking your Basal Body Temperature (BBT) will help you pinpoint which patch of fertile mucus was related to ovulation.

Some women notice that their cervical mucus becomes wet or almost egg-white like again right before menstruation. Obviously, this isn’t a sign of impending ovulation. In addition, if you never or rarely notice wet or egg-white consistency cervical mucus, let your doctor know. Infertility can sometimes be caused by something referred to as hostile cervical mucus.
