Cervical Mucus Stages

When a person is in the fertile phase, its cervical fluid is thin, slippery and watery which is very similar to a white egg. Cervical mucus changes occur throughout all the menstrual stages. This kind of discharge signifies healthy and regular ovulation.

What is cervical mucus?

Cervical Mucus is a type of fluid which gets released into the vagina. It functions diversely, for instance, preventing the vagina from infection and making it lubricated. The occurrence of various hormonal shifts influences the amount, texture, and appearance of an individual’s cervical mucus, throughout the whole process of the menstrual cycle. Although the cervix always produces some amount of mucus, it makes more observable before and after ovulation. So, if a person notices an increased amount of vaginal discharge, they may be seeing fertile cervical mucus.

What is fertile discharge?

The fertile discharge is thin, clear, white, and slippery, the same as an egg white. This type of discharge signals that ovulation is approaching. Fertile cervical fluid helps sperm to move the cervix up and help it to fertilize an egg. It also keeps the sperm healthy during the entire journey. Women usually notice fertile discharge a few days before ovulation. The ejection may become wetter and more slippery over several days. After the ovulation process, the amount of discharge usually tends to decrease.

          A ripening egg that grows inside an enclosure is called a follicle, located inside the uterus. The follicle grows at a certain age and produces estrogen. When the follicle starts to rupture, the body ovulates and releases an egg. The estrogen that the follicle produces; it softens the cervix and opens it slightly. Produced estrogen also changes the texture of cervical fluid, making it more able to support fertility.

Cervical mucus timeline:

Every woman has a slightly different cervical fluid. So, to detect the fertile discharge, a person has to monitor their cycle for several months. The numbers of days that discharge changes vary from person to person. Those women who ovulate later in their cycle, for instance, she should expect her fertile discharge after day 14. In general, the discharge cycle follows this pattern:

  • Early cycle (days 1–5): These 1-5 are the days, when menstruation occurs.
  • Post-period (days 5–10): Firstly, there may be little or no discharge, but sticky, glue-like fluid may release. This phase is known as low fertility phase.
  • Pre-ovulation (days 10–14): The body start produces more estrogen. A sort of sticky fluid may look thin and cloudy. Ultimately, it gets slippery and begins to look like egg whites.
  • Ovulation (day 14): On the day of ovulation, many notice that their cervical fluid is very wet and viscous. A person may be able to stretch the fluid an inch or more between their fingers.
  • Post-ovulation (days 14–22): After the process of ovulation, the body releases the hormone that is progesterone, which makes the cervical fluid dries up. The excreted fluid may look cloudy at first, and then becomes thicker.
  • Pre-period (days 22–28): As a period about to come, the discharge may have a glue-like consistency again. There can be very little or no excretion of fluid 1–2 days before menstruation. Some women notice the fluid spots just before getting their periods. Ovulation plays a significant role in governing the consistency of the cervical fluid. A person who does not ovulate may notice fewer or very fewer changes in their vaginal discharge. The woman who ovulates very late or very early may find that their cycle does not follow the “regular” schedule.

When is a person most fertile?

The fluid of fertile cervical is a good signal of increased fertility. Anyone trying to get pregnant should have intercourse during the time when they observe this fertile cervical fluid discharge. Doctors define this as the “fertile window.0”. An egg only lives for 12–24 hours after getting ovulated; but sperm can survive for much longer than that, for instance like for often 3–5 days in fertile cervical fluid. This illustrates that, for that woman who wishes to become pregnant, the best time for them to have intercourse is right before ovulation, as sperm can stay in the reproductive tract for several days. If they are already present there at the time of ovulation occurs, they can immediately fertilize an egg.

How to check?

To determine the fertility through discharge, there is a need to check the appearance of the cervical fluid at least once a day, beginning on the first day after getting periods started. It can help the women to keep track of daily changes in a diary or to use a monitoring application. To check for the discharge of the cervical fluid:

•    After using the bathroom, clean the area around the vagina to remove any excess pee, which can change the appearance of the cervical fluid.

•    Use the toilet paper to pat the area around the vagina. Women should note the visible fluid.

•    Wash the hands properly and gently insert a finger about half an inch into the vagina.

•    Remove the finger and notice the color, texture, and prevailing appearance of the cervical fluid.

•    If the cervical fluid is clear, thin, watery, and stretchy in appearance, it may be fertile cervical discharge.

There are several other factors which can influence the way that cervical fluid looks, that is why a woman should monitor the appearance and uniformity over time, to get an idea of what is normal for them. Some woman finds that their cervical fluid looks different after having intercourse. For example, when the semen gets mixed with the vaginal fluid, this can change the aspect of vaginal discharge. Soap, lubricants, and various other products can also result in changes.

          Some women produce less fertile cervical mucus, so they may not notice it and there also others who produce no fertile cervical mucus and this can create a problem with ovulation. There are also various some medical conditions, such as polycystic ovarian syndrome or PCOS which makes ovulation less likely. Women who are underweight also cause the body not to ovulate. As a woman reaches a menopause level, they may be able to ovulate less frequently. Some women run out of eggs very early, which a doctor diagnose and define it as a decreased ovarian reserve. This can cause a woman to ovulate irregularly.


Keeping a track of the appearance and consistency of cervical fluid can help a person determine when they are fertile. This method is most reliable when a person has monitored changes in fluid for several cycles. When it comes to cervical fluid, everyone has a different “normal.” A person who knows their usual pattern can more easily spot signs that they are about to ovulate. Many people also use other methods of tracking fertility, such as basal body temperature monitoring and ovulation testing.

         A combination of approaches can provide more certainty about ovulation. It is important to note that having fertile cervical fluid is not a sure sign of fertility. The body may release high levels of estrogen, even though a person does not ovulate. However, in general, if a person does not ovulate, they are much less likely to have fertile cervical fluid. While home methods of monitoring ovulation may help, the only way to verify ovulation is to see a doctor or midwife.
