Cervical mucus is the discharge from the cervix. This mucus has different characteristics depending on the phase of the menstrual cycle in which the woman is because the hormones that regulate the cycle influence its consistency and appearance and make it different at each stage.
Therefore, a woman observing what her cervical mucus looks like can guide her as to when ovulationoccurs. This will help you to calculate your fertile days and, therefore, to achieve pregnancy if you wish to do so.

As mentioned, cervical mucus undergoes a series of changes throughout the menstrual cycle. These modifications in their characteristics serve to facilitate or hinder the passage of spermatozoa, depending on the moment of the menstrual cycle in which the woman finds herself:
The follicular phase of the menstrual cycle is from the first day of menstruation (day 1 of the cycle) to the day of ovulation (day 14 in a regular 28-day cycle).
Thus, during the follicular phase, it is not yet necessary to allow sperm to enter the uterus, since ovulation has not yet occurred. Therefore, cervical mucus will be thick, viscous, sticky, and rather opaque.
The Fertility Awareness Method (fam)
However, as ovulation approaches, the discharge from the cervix will begin to change its characteristics as the body begins to prepare for possible fertilization and pregnancy.
The time of ovulation and the days around it are the most fertile period for women since it is easier for the encounter between egg and sperm to occur.
For this to be possible, the cervical mucus modifies its properties in the periovulatory period, allowing sperm to enter the cervical canal.
The Symptothermal Method Explained
The days close to ovulation are the most fertile days for women, so it is advisable to have sex during this period if you are looking for pregnancy.
Due to the influence of estrogens, the cervical secretion increases in quantity and becomes progressively clearer or transparent. In addition, the cervical mucus becomes more elastic, with a more watery consistency and very similar to that of raw egg white.
On the other hand, if taken between two fingers, the cervical mucus of the ovulatory period can separate forming thin threads without breaking, a characteristic known as
Cervical Mucus And Cervix Observations [how To Guide]
At this stage, progesterone levels are high, which causes the characteristics of the cervical mucus to change again. Again, in the luteal phase the mucus is whiter, thicker and thinner, acquiring a creamy appearance.
It should be noted that the appearance of cervical mucus may vary due to factors other than the menstrual cycle. As an example, hormonal contraceptives can affect cervical mucus by interfering with the hormone levels of the menstrual cycle.
On the other hand, cervical mucus analysis can also serve to alert us to possible infections in the female reproductive tract. If the mucus is yellow or greenish in color and has a changed odor, it may indicate a sexually transmitted disease (STD) that could also affect fertility.
Natural Family Planning
To check the color and texture of the cervical mucus and, thus, to be able to estimate whether the woman is in her most fertile days, it will be necessary to take a small amount of mucus by inserting the index finger into the vagina. For this purpose, it is essential that the hands are properly washed.
Subsequently, while the cervical mucus remains on the index finger, it will be important to touch it with the thumb and separate both fingers to evaluate its elasticity and philance.
It may be useful to take samples of cervical mucus at different phases of the menstrual cycle and even on a daily basis. In this way, the woman will be able to make a comparison that will help her to interpret whether she is in her most fertile period or not.

However, when the fertile period has not yet arrived, some dryness is common. This is because the cervical mucus is scanty, which can make it difficult to collect the sample.
The analysis of cervical mucus can be a good indicator of a woman's most fertile period, as long as one learns to correctly differentiate each of its textures and the changes in elasticity it undergoes throughout the menstrual cycle.
Thus, by recognizing the characteristics of the cervical mucus on the days close to ovulation, a woman can calculate her most fertile days to increase the frequency of sexual intercourse in order to achieve pregnancy.
What Is The Cervical Mucus Method?
For this, it is important to keep in mind that the oocyte can be fertilized for approximately 24 hours after ovulation. However, sperm can survive in the female reproductive tract for about 4 days in the ovulatory period. This is why the most fertile days correspond to the 3-4 days prior to ovulation and the day after.
However, it should be kept in mind that, despite ovulation occurring, there may be other factors that prevent fertilization or the achievement of pregnancy, such as having blocked tubes or poor seminal quality.
Therefore, if pregnancy is not achieved after a year of frequent and unprotected sexual intercourse, it is advisable to go to an assisted reproduction clinic to perform the necessary fertility tests on the couple.
Billings Ovulation Method
Cervical mucus is produced by the mucous glands present in the cervix. Because the production of these glands is influenced by ovarian hormones, the characteristics of the mucus will change throughout the ovarian cycle. In addition to the hormonal variations of the cycle, cervical mucus can be an indicator that helps the patient and the gynecologist to know or suspect an abnormality.
Variations in its characteristics, such as odor and color, allow us to suspect colonization by different bacteria. Changes in cervical mucus to a brown, brown or dark color always indicate the presence of blood in small amounts.
When blood is present in the vagina, in small amounts, there is an interaction between the usual germs of this organ and the components of blood, mainly hemoglobin. As time goes by, the intense red color of the blood changes and becomes darker and darker.
What Your Cervical Fluid Can Tell You About Your Reproductive Health
The presence of a dark cervical mucus outside the episodes considered physiological should awaken in the woman the concern to consult her gynecologist to assess the need or not to study and the conduct to follow.
Yes, the odor can change from one woman to another and even in the same woman, depending on the day of the cycle in which she is. However, if this odor changes suddenly and smells bad, it may be indicative of an infection, so it will be advisable to see a gynecologist.
Yes, cervical mucus changes its density, color and texture throughout the menstrual cycle, as it depends on hormonal variations. In addition, these changes in cervical mucus provide information about the period when pregnancy is most likely to occur.

La principal ventaja que puede ofrecer el método del moco cervical para evaluar los días fértiles es que es un método fácil de realizar y económico. La mujer puede analizar su secreción cervical de forma casera y sin ningún tipo de instrumentación ni material necesario.

This definition refers to the pattern left by the spreading and drying of the mucus in the fertile stage, i.e., the days close to ovulation.
This fern leaf-shaped pattern creates channels through which the sperm can pass. The passage of male cells through these ducts is essential for their capacitation and activation.

The Billings method is a natural way of birth control that is based on the changes in cervical mucus that we have explained. In this way, it predicts the time of ovulation and, therefore, the most fertile period with the highest probability of pregnancy.
As we have seen in this article, cervical mucus undergoes a series of changes during the menstrual cycle. For this to be carried out correctly, it is essential that there is a perfectly regulated hormonal balance.
