2 4 day cycle what phase. Menstrual cycle. menstrual period of the cycle

The menstrual cycle consists of several phases. The phases of the cycle of menstruation by day are divided by gynecologists as follows:

• menstrual phase: 3 to 6 days;
• the second phase is follicular: about 14 days;
• ovulation phase: about 3 days;
• luteal phase: 14-16 days.

menstrual phase

The beginning of the menstrual cycle should be considered the first day of the onset of menstruation. This physiological process occurs due to the rejection of the endometrium of the uterus. Bloody discharge in each woman can have a different character: from heavy bleeding to smearing. When the endometrium of the uterus is shed, the body prepares for the formation of a new egg. Every menstrual cycle is a preparation female body to fertilization and pregnancy.

The first phase of the cycle is accompanied by pain in the lower abdomen, weakness, drowsiness and irritability. These days it is better to refrain from physical activity and, if the life schedule allows, more rest and stay in a calm environment.

Painful sensations can be reduced by such drugs: Tamipul, Spasmalgon, No-shpa, Paracetamol. It should be noted that all medicines should be taken only after the recommendation of the doctor.

In healthy women, these symptoms appear in a mild form. Often the cause of painful menstruation can be:

1. Heredity. If a mother or grandmother suffered from pain before menstruation, then there is a high probability of these manifestations in the next generations.
2. Pathology of the uterus: bend, curvature or underdevelopment of the organ. In this case, the pain syndrome will accompany menstruation even in women who have given birth.
3. The occurrence of tension in the pelvis due to contraction of the uterine muscles.
4. Compression of nerve endings due to enlargement of the uterus.
5. Increased sensitivity of the body to ongoing physiological processes.
6. An increase in prostaglandin hormones, which act on the genitals and thus cause pain.
7. Stagnation of blood in the pelvis and swelling of the tissues.
8. Intrauterine device. It can cause intense contraction of the muscles of the uterus, resulting in pain.

However, very often painful periods are associated with inflammatory processes in the pelvic organs. To make sure that these manifestations are absent, it is necessary to be examined by a doctor and, if necessary, undergo a course of treatment.

During menstruation, a healthy woman loses about 10 ml of blood. To avoid anemia, these days you should eat more fruits, vegetables containing iron, and also take a complex of vitamins. This applies primarily to teenage girls, whose body is not yet fully formed.

During this period, fresh air and a calm environment are useful for a woman. Family members should not forget that during the period of menstruation, complex hormonal changes, because of which she perceives everything very sharply, is irritable and unbalanced. Therefore, the best medicine these days for a woman will be support and understanding from relatives.

Follicular phase and ovulation

The second phase of the monthly cycle lasts about 2 weeks after the end of bleeding. However, stress and lifestyle changes can interfere with the normal duration of this phase.

During this period, the ovaries produce a hormone that stimulates the development of follicles, FSH. In the dominant follicle, the ovum subsequently matures.

The follicular phase is characterized by the release of the hormone estrogen, which promotes the renewal of the uterine wall. This hormone affects the biological environment in the cervix, making it insensitive to sperm. Nature decreed that during this period the female body is preparing for fertilization, and premature ingestion of sperm is undesirable.

Estrogen is considered the main beauty hormone. Skin, hair and nails become strong and beautiful. During this period, any cosmetic procedures are appropriate.

On day 14, the body releases the luteinizing hormone LH, while the production of the hormone FSH decreases. The LH hormone has a beneficial effect on the mucus in the cervix, making it receptive to sperm. Under the influence of this hormone, the maturation of the egg ends and it is released from the follicle.

This process is called ovulation, which lasts from 2 to 4 days. This is the most favorable time for conception. Many girls who want to get pregnant calculate these days according to the calendar.

The mature egg moves through the fallopian tubes, where it waits for a meeting with the sperm within 2 days. Spermatozoa are able to live for about 5 days, so if sexual intercourse occurred shortly before ovulation, then there will be a high probability of fertilization of the egg.

In this phase, the girls' appetite increases, which threatens speed dial weight. This is due to the accumulation of the necessary nutrients in the body in case possible pregnancy. At this time, it is better to increase the consumption of dairy products and plant foods.

The probability of conception is possible already from the 9th day of the cycle. There is even a certain theory of conception of the desired sex of the child. If parents dream of a girl, then sexual intercourse should be performed before ovulation, since the X chromosome, which determines the female sex, is more viable. And if the desired sex of the child is male, then it should be conceived on the days of ovulation - on the 12-14th day of the cycle.

In ancient Eastern teachings, it is said that before ovulation, a woman accumulates energy, and after ovulation, it is redistributed. Saving energy allows a woman to achieve harmony and peace of mind.

Women during the period of ovulation have a special smell that attracts men. She shines with beauty, health, and her sexuality these days is at the highest level.

Luteal phase of the menstrual cycle

After the release of the egg, the empty follicle, or corpus luteum, begins to produce the hormone progesterone. It prepares the endometrium of the uterine cavity for the introduction of a fertilized egg. At this time, the production of the LH hormone ends and the cervical mucus dries up.

The luteal phase lasts 14 to 16 days. The female body is preparing for the introduction of the embryo. This process occurs within 6-12 days after fertilization. As soon as this has happened, the production of the hormone chorionic gonadotropin begins. It supports the function of the corpus luteum, which produces progesterone throughout pregnancy, which ensures the normal bearing of the child.

Modern pregnancy tests are sensitive specifically to human chorionic gonadotropin, which is called the pregnancy hormone.

If fertilization does not occur, then the corpus luteum and the egg die off, and the production of progesterone stops. The endometrium of the uterus also begins to collapse.

From the 20th day of the cycle, the concentration of luteinizing hormone decreases and the corpus luteum begins to reverse development in the ovary. It is believed that from this day the probability of getting pregnant becomes minimal.

At the end of the luteal phase, the top layer of the uterus begins to shed and subsequently exits with menstrual flow. This is the beginning of a new cycle.

In the final phase of the menstrual cycle, the metabolism slows down. A week before the onset of menstruation, the work of the sebaceous glands of the skin intensifies. Girls get skin rashes. These days it is advisable to refrain from physical activity, as the connective tissues become more vulnerable.

PMS - premenstrual syndrome - is reflected not only in appearance but also on the woman's mental state. As a result of a drop in hormone levels, a woman becomes vulnerable and vulnerable, she needs the support and understanding of her relatives.

The mammary glands increase in size, there is daytime sleepiness, a feeling of anxiety or apathy. Gynecologists advise these days such "medicines" as sex and chocolate. However, in some women during PMS, libido decreases, so chocolate remains, which contributes to the production of the hormone of happiness.

The length of the menstrual cycle is different for every woman.

Therefore, the duration of the monthly phases for each woman may be different.

Cycles lasting from 21 to 32 days are considered normal.

In the article, we will consider what phase happens on the 22nd day of the cycle.

The menstrual cycle is the time interval that passes between successive periods. This segment is divided into phases, which are characterized by their own specifics, which determine the state of the woman's body. If a woman is guided in the phases of her cycle, she will be able to understand herself well, explain changes in well-being, mood swings and other features.

Often ladies ask the doctor - on the 22nd day of the cycle, what phase?

Menstrual cycle: description

The menstrual cycle is understood as a time period, the beginning of which is the first day of the onset of menstruation, and the end is the day before the next menstruation. This process is repeated every month in all women with a normal state of health, excluding breastfeeding and pregnant women.

Every month, nature prepares a woman for the possible conception of a child and does everything to ensure that the child finds herself in favorable and comfortable conditions in which he can develop and grow harmoniously.

When a girl is born, there are many eggs in her ovaries (about two million), but by puberty there are a maximum of four hundred thousand. As a rule, one egg is spent during one cycle.

The regular cycle of menstruation is impossible to imagine without the participation of hormones and structures of the brain of the head. The sequence of phenomena that are observed during the normal cycle is explained by the close relationship between the functioning of the endometrium, hypothalamus, ovaries and anterior pituitary lobe. Its average duration is 28 days. However, a cycle that lasts between 21-35 days is also normal. On the 22nd day of the menstrual cycle, which phase, we will describe below.

Follicular phase

The onset of bleeding, that is, the first day, means the onset of the follicular stage. It covers a period of time of 14-15 days, ending with the arrival of ovulation. The body of a woman at this stage is cleared of an excessive amount, the uterine cavity is freed from the old endometrium, and a follicle matures in the ovary. The necessary conditions are created for the growth of the embryo, the new endometrium grows and thickens.

What phase is on the 21st and 22nd day of the cycle, every woman should know.

Features of the ovulatory phase

The second phase of the menstrual cycle is understood as the onset of the period of ovulation, which is due to the concentration of luteinizing hormone in the female body. This circumstance causes the destruction of the follicle, as a result of which the finished egg enters directly into the uterine tube. It is this period of time that is most successful in order to conceive a child. The duration of the ovulation phase is set individually, it can last from 16 to 32 hours.

Drawing pains in the lower abdomen, emotional instability - many women are forced to face such symptoms on the first or second day. Also, the appearance of headaches is not ruled out.

What phase is the fifth day of the cycle?

This is still the same follicular stage, but the woman's well-being gradually returns to normal, along with it her mood improves, irritability goes away.

From the seventh to the eleventh day, an excellent mood is observed in almost all women. This period is characterized by satisfaction, big plans for the future, high efficiency.

So, let's figure it out, on the 22nd and 23rd day of the cycle, what phase?

The luteal phase - what you need to know about it

Periods of the cycle of menstruation and hormones are closely interconnected, due to which the next phase stands out. Ovulation ends and is replaced by the luteal stage. The duration of this period has an average of two weeks, it ends when the next menstruation comes. The preparation of a woman's body for pregnancy does not stop, so she can still come.

The girl in the first three or four days of this phase enjoys excellent health, is distinguished by her ability to work and cheerfulness.

What phase falls on the 21st day of the cycle?

This is the same luteal period, however, the state of the woman's body begins to deteriorate sharply, which is due to natural processes in the body and should not be surprising.

In the absence of fertilization of the egg, the high concentration of progesterone and estrogen stops. The female body is gradually preparing for the onset of the next menstruation. Premenstrual syndrome, which has gained notorious popularity, is considered to be the most negative period in the life of all women.

Day 22 of the cycle - what phase?

It enters the second half of the luteal period, when such manifestations as emotional instability (dramatic improvements or deterioration in mood), depressive mood are noted. There are also external symptoms, many women note lumbar pain, increased sensitivity of the mammary glands, swelling of the face and limbs. By the 28th day of the cycle, all unpleasant phenomena disappear.

Around the 22nd day of the cycle, the maximum content of progesterone is observed. During this period, the endometrium thickens even more, only due to the formation of a secret by the uterine glands and an increase in cell sizes (the third stage of secretion). At the end of the luteal phase, its thickness can be from 12 to 14 millimeters.

If conception does not occur, the concentration of hormones (LH, FSH, progesterone, estrogen) begins to gradually decrease. Their minimum amount starts menstruation, and the next cycle begins. This process can change due to bad habits, stress and past illnesses. What phase is on the 22nd and 24th day of the cycle is now clear.

Period diary: why is it needed?

Gynecologists advise all women to keep a diary of their menstrual cycle. Currently, you do not need to start a special notebook for this. Now you can simply install the application on your phone and do not forget to enter the necessary information there. This diary is needed in order to know the average time of one cycle. It will also help control the level of progesterone. What is the phase on the 22nd day of the cycle, we explained.

The norm of progesterone by day of the menstrual cycle

The rate of progesterone in women is set depending on the time of the menstrual cycle. Each phase will have its own meaning. In the luteal phase, progesterone reaches its maximum levels - this indicates the beginning of ovulation and uterine preparation for egg implantation.

With a low level of the hormone at this time and the onset of fertilization, a spontaneous miscarriage will occur. Women who are planning a pregnancy, which is why they must control the content of progesterone during the second phase of the cycle.

The doctor prescribes a blood test on the 22-23rd day of the cycle, however, for a more detailed picture, it is recommended to take it several times in a row to monitor the dynamics. So, what level of the hormone is normal? It must be said that women taking hormonal contraceptives will have significant differences in performance. Each stage of the cycle has its own standard values:

• From 1 to 15 days - from 0.97 to 4.73 nmol / l.
• From 17 to 22 days of the cycle - from 2.39 to 9.55.
• From 22 to 29 days - from 16.2 to 85.9.

But not all women will be exactly like that.

The indicator of the norm for those who take hormonal contraceptives:

• from 1 to 15 days - up to 3.6 nmol / l.
• from 17 to 22 days of the cycle in the luteal phase - from 1.52 to 5.45.
• from 22 to 29 days - from 3.01 to 66.

In the postmenopausal period, a woman's hormonal level should be in the range of 0.32-2.51.

If pregnancy has come, the hormone is growing rapidly, and a pregnant woman will have the following indicators:

• from 1 to 13 weeks of pregnancy - from 14.9 to 107.9;
• from 14 to 27 - from 61.7 to 159;
• from 28 to 41 - from 17.3 to 509.1.

The hormone level suddenly drops two days before delivery, reaching a value of 2.3. This is necessary so that the uterus is able to contract and thereby stimulate labor activity. However, the amount of progesterone will still be high, as it takes part in stimulating milk production.

Increased and reduced progesterone levels: what does it affect?

With a reduced amount of the hormone in the first trimester, a miscarriage occurs, as the uterus shrinks sharply, the endometrium is not ready enough to keep about fertilized egg. However, with a problem that is only in progesterone, it can be solved with special means that are prescribed by a gynecologist.

• lack of ovulation;
• chronic inflammation of the ovaries;
• irregular cycle of menstruation;
• violation of the functioning of the corpus luteum;
• adrenal disease.

With a decrease in the content of progesterone, the level of estrogen also changes - it rises, and as a result, the woman has:

• convulsions;
• sweating;
• puffiness;
• sleep disturbance;
• weight gain.

Estrogen should normally be in the range of 11-191 pg / ml. During menopause in women, its content is 5-90 pg / ml.

If the level of progesterone in the female body is elevated, the following conditions may be the causes:

Doctors say that progesterone is the most important hormone for a woman. If there are problems with pregnancy and conception, tests for its content in the blood are given first. If necessary, synthetic substances are prescribed that replace the hormone or stimulate its production.

To determine the level of progesterone, it is necessary to take a blood test. However, before delivery, you should consult with a gynecologist who will tell you right choice day. Often, doctors prescribe a study on the twentieth day, but this is not entirely correct, since the following factors must be taken into account:

It must be remembered that during observation during the period of blood donation, ailments, as well as treatment with certain drugs, you can get unreliable results. In this case, they are retaken in a month or at the end of therapy.

We examined which phase is on the 22nd day of the cycle.

During the menstrual cycle, the reproductive system is rebuilt, which affects the well-being and psycho-emotional state of a woman. Cyclic changes are necessary to prepare the body for conception. Every woman knows what critical days are, but only a few have an idea about the duration and phases of the cycle.

Sometimes ignorance leads to the development of serious pathologies, because a woman is not able to recognize a deviation from the norm and consult a specialist in a timely manner. To avoid this, you should get acquainted with the characteristics of the female body, having studied the phases of the menstrual period and the manifestations of possible pathologies.

Menstrual cycle - what is it?

The menstrual cycle is the period that begins on the first day of menstruation and ends with the arrival of the next menstruation. Since every woman has it in her own way, the concept of his "normality" is rather vague. To characterize the menstrual cycle, experts use the following concepts:

• How long is the cycle. The time interval between the beginning of two subsequent menstruation: 1 day of menstruation is the beginning of the next cycle and the end of the previous one. Many women mark the beginning of critical days in a special calendar and, by counting the number of days between menstruation, know the duration of their cycle. Keeping a calendar allows you to control the stability of the cycle and clearly demonstrates any failures. If the menstrual cycle lasts from 25 to 35 days, this is the norm. In 60% of women, the cycle length is 28 days.
• duration of menstruation. Menstruation lasts from 3 days to a week. Only 25% of women have periods longer than 7 days.
• The volume of blood loss during menstruation. Normal values ​​​​are from 40 to 150 ml. If a woman uses more than 4 sanitary pads every day, this is normal. Menstrual flow should not contain a large amount of mucus, clots. If the monthly pass normally, the amount of discharge gradually decreases. Heavy bleeding rarely lasts more than 3 days. On such days, a woman may feel a pulling pain in the uterus.

In 30% of women who do not have gynecological pathologies, the menstrual period passes according to individual "standards", without affecting the reproductive functions of the body. This feature is noted from the first menstruation and continues until the onset of menopause.

Phases of the cycle: what happens in the body?

Developed under the influence of hormones, cyclic changes affect the physiology of a woman, her emotional state. The phases of the menstrual period are structural and hormonal changes of a cyclic nature that occur in the female body, ensuring the implementation of the reproductive function. Influencing the sexual sphere and the work of the whole organism, the hormonal function of the ovaries plays a key role in the foundation of the cycle.

The central part of the nervous system (pituitary gland, hypothalamus) is involved in the formation of the menstrual period. At each stage, hormonal changes occur in the ovaries, leading to a change in the structure of the endometrium.

The pituitary gland produces hormones that affect the functioning of the ovaries: FSH (to stimulate the follicle), LH, prolactin. According to the phases of the cycle, the hypothalamus releases releasing hormones that enter the pituitary gland during the cycle. Pituitary hormones stimulate the maturation of the egg, ensuring the implementation of the reproductive function.

Conventionally, the 1st and 2nd phases of the female period have the same duration, but different structural and hormonal changes. Almost always each of them lasts about 14 days. Since ovulation occurs between phases, it is considered to occur in the middle of the cycle.

First phase

The follicular phase begins with the next menstruation and ends with a short period of ovulation. At this time, the egg begins to grow and develop. Of the many liquid vesicles located in the female ovaries, those are outlined that will increase this month.

The development of the follicle is supported by estrogen, the production of which gradually increases. On the 7th day of the cycle, one follicle grows larger than the others and continues to grow the egg. The rest of the bubbles stop growing. Gradually, the level of estrogen reaches its maximum level, the diameter of the follicle grows to 20–25 mm, and the hormone LH is released, which is a harbinger of ovulation.

Second phase

If conception did not occur during ovulation, after a day the egg dies and the luteal phase starts, which ends with the beginning of the next critical days. From the fragments of the burst follicle, a cell begins to grow, which is transformed into a temporary yellow gland that produces progesterone.

Under the influence of the pregnancy hormone, the endometrium becomes softer, "breathable" and thick enough for the fetal egg to be firmly embedded in the wall of the reproductive organ. If conception occurs during ovulation, the second phase is responsible for the onset and development of pregnancy until the placenta is formed. If fertilization does not happen, by the beginning of the next cycle, the temporary gland will disappear.

When do phases start and how long do they last?

Numerous studies have proven that the value of the second phase is 14 days. Any deviation from the norm indicates the presence of a pathological failure in the female reproductive system. The size of the first phase is individual for each woman. With a 28-day cycle length, the first phase lasts and develops as follows:

• the first two days of menstruation - there are pains of a pulling nature in the lower abdomen, spotting, mood worsens, performance decreases, irritability increases;
• from 3 to 6 days the emotional state is normalized, the state of health improves;
• from 7 to 12 days, a woman has a good mood, increased working capacity and sexual desire;
• From the 13th to the 14th day, the body prepares for ovulation.

If the first phase has a different duration, the development scheme fits between 7 - 21 days. Then the second phase begins smoothly, the duration of which is always 14 days:

• From the 15th to the 22nd day, a stable psycho-emotional and physical state is noted. If, however, conception occurred during the period of ovulation, on the 20-22nd day, when the embryo is fixed to the uterine wall, scanty spotting and mild abdominal pain may appear.
• If fertilization does not happen, from the 23rd to the 28th day, the woman has signs of premenstrual syndrome: a sharp change in mood, irritability, depression, swelling of the mammary glands.

Possible pathologies: when to see a doctor?

The menstrual cycle must be stable, and any discrepancies in its duration should not be more than 72 hours. If the regular duration of both phases is 25 days, and in some month it has increased to 32 days, this indicates a malfunction in the body and requires specialist advice.

It happens that menstrual disorders are provoked by the formation of functional cysts. As a rule, such neoplasms go away on their own. If this phenomenon is regular, it is necessary to donate blood to determine the level of hormones.

For several periods, the nature of the discharge in the ovulation period of time almost does not change. If intermenstrual bleeding appears, you should consult a gynecologist, since this symptom may indicate the following pathologies:

• polyps;
• myoma;
• hormonal disorders;
• polycystic;
• hyperplasia of the inner layer of the uterus;
• vaginal trauma;
• long-term use of oral contraceptives.

During ovulation, the cervix becomes softer and opens. Since the secretions contain remnants of the rejected endometrium and blood after critical days, they have a brownish tint. If this happens infrequently, and the discharge is spotty and short-lived, there is no reason to panic. At serious illnesses liver, vascular fragility, vaginal infections, dark-colored discharge appears in the middle of the cycle.

Chlamydia, gonorrhea, candidiasis are accompanied by yellow discharge. To this symptom is added a repulsive odor, vaginal itching, swelling, redness of the labia, soreness during sex.

If the discharge changes color, viscosity, smell and is profuse, a woman should consult a doctor. Health care necessary when the following symptoms appear:

• temperature rise;
• itching in the vagina;
• pain in the abdomen and lower back.

If the discharge has a dirty red tint and an unpleasant odor, this may indicate a neoplasm in the female genital area. This symptom is a good reason for visiting a gynecologist and a subsequent examination.

About what the menstrual cycle is, what parts it is divided into, how it is connected with the chances of pregnancy, any woman should understand, perhaps, from the time of her maturation. And although this is not considered an area of ​​​​special, strictly medical knowledge, but is a sphere of literacy in relation to their health, a huge number of women “float” in this matter. And methods of contraception, the so-called natural ones, are not a 100% guarantee of protection against pregnancy. Why? This issue should be considered at the level of physiology, having understood all the risks and opportunities.

What is the probability of getting pregnant on the 4th day of menstruation

What is commonly called menstruation (another name is regulation) is one of the periods of the cycle, accompanied by the release of mucous bloody formations from the uterus. This is how, for centuries, the female body parted with the rejected endometrial cells that lined the inner surface of the uterus. These and strong discharges, as well as the unfavorable environment in the vagina, do not allow you to get pregnant at the very beginning of menstruation - these conditions are detrimental to spermatozoa.

Menstruation lasts from three to eight days, and everyone passes in their own way. The monthly cycle is divided into several phases, between them ovulation occurs. And this time, which is approximately 24 hours, is the most favorable for pregnancy. If it does not occur, after about 14 days, the rejection phase of endometrial cells will begin, which have not accepted the egg.

The reproductive system of the female body is a complex mechanism created by nature to continue the human race. From the moment of puberty to the onset of menopause, the purpose of the beautiful half of humanity is to bear and give birth to a child. To prepare for this event, processes invisible to the naked eye take place every month, which are called the phases of the menstrual cycle.

First phase of the menstrual cycle

The cyclical period itself for each woman is an individual phenomenon. Its beginning is considered the first day of menstruation, and the duration ranges from 21 to 35 days. The average ideal value is considered to be 28 days.

Cycle graph - clearly shows the development of the egg (follicular + ovulation + corpus luteum)

Start of egg growth

The first phase of the menstrual cycle is responsible for the beginning of the growth and development of the egg, it is called the follicular. In the ovaries of a woman there are a large number of rudiments of liquid vesicles. Together with the first day of monthly bleeding, those of them who will grow in the current month are outlined.

Estrogen production

Phase 1 of the menstrual cycle is a period where, under the influence of follicle-stimulating hormone, the production of estrogen gradually increases, which supports the development of follicles. Approximately on the 7th day of the cycle, one bubble significantly outperforms the others in all respects, this is for them something like a signal to stop growth and reverse development. And the leader of the race continues to grow the egg, reaching a limiting size of 20-25 mm in diameter. By this time, estrogen levels have reached their highest point, which provokes the release of luteinizing hormone (LH), a precursor to ovulation.

Features of ovulation

As soon as the growth of LH is fixed, the ovulatory phase is approaching, it is like a separation of the two halves of the cycle, which can be called the 3rd phase of the menstrual cycle, although rather it is a dividing line between them, located in its middle.

Ovulation is the shortest segment in a cycle of 24-36 hours, but the most significant. It was at this time that the mature egg breaks through the wall of the ovary and rushes into fallopian tube, where she will meet with the sperm. If such a meeting does not happen, the cell dies in a day.

Second phase of the menstrual cycle

Once the egg has left the ovary, the second phase of the menstrual cycle begins. At the site of the rupture of the follicle, the corpus luteum begins to grow, producing progesterone, which helps fertilization occur, causes the endometrium to become loose, soft and thick enough so that the fetal egg can easily penetrate its wall.

luteal phase

The second segment is called the luteal phase of the menstrual cycle, what it is and why it is called that is simply explained. From fragments of the tissue of the liquid vesicle and vessels, special cells begin to grow, which have a yellow color. Gradually, the cells turn into a temporary gland that produces lutein hormone, the hormone of pregnancy. The gland is called the corpus luteum, and since it plays a leading role in the second period of the cycle, the phase is also called the luteal.

Progesterone production

Phase 2 of the menstrual cycle is the process responsible for the onset and development of pregnancy with the help of progesterone produced by the gland until the placenta is formed, which takes over. In the absence of conception, by the beginning of a new cycle, the corpus luteum disappears.

Very detailed about the menstrual cycle

How long are cycle phases

Now let's return to the digital values ​​​​and analyze the phases of the menstrual cycle by day. We remember that the boundaries of this monthly phenomenon range from 21 to 35 days. Numerous studies have shown that its second half is constant and is 14 days. It can change its duration in the direction of decreasing or increasing only if pathological abnormalities occur in the female reproductive system. But the first phase - the value is different for each lady.

Let's analyze in detail - how many days each phase lasts and how it is characterized

Now let's see how our girls feel about how the first phase of the menstrual cycle proceeds and how many days it can take with a 28-day length:

• The first and second days are not encouraging, almost all of our ladies suffer from pain in the lower abdomen, and of course, spotting also does not improve mood, performance decreases, the usual rhythm of life decreases.
• From 3 to 6 days, the state and physical well-being begin to slowly stabilize.
• 7-12 days pass in a good mood, the zeal for work increases, doing the usual things, sexual desire and a lot of other positive emotions appear.
• 13-14 day - waiting for ovulation.

With a different duration of the rhythmic period, a similar table fits between 7-21 days.

And we are smoothly moving into the second phase of the menstrual cycle, and how many days it lasts, we have already determined as an established constant value - 14 days.

From 15 to 22 days, the state of health and mood is excellent. But sometimes at the end of this interval in some women after the fertilization has taken place, the moment the embryo is fixed in the uterus will be marked by the release of a few drops of blood and the appearance of a slight pain in the lower abdomen during the day.

If the egg dies without meeting the male cell, then signs of premenstrual syndrome can be observed from 23 to 28 days. They are expressed in irritability, frequent mood swings, tearfulness, a tendency to depression, swelling and soreness of the mammary glands.

Table of phases of the menstrual cycle

If you link these days to the possibility of fertilization, then the table of the phases of the menstrual cycle looks like this:

• Starting from the first day of menstruation and up to day 11 with a 28-day period, fertilization is unlikely.
• The maximum time for conception falls on the 12-16th day. It is in this time period that if you want to get pregnant, sexual intercourse can be crowned with success, in the form of the birth of a new life.
• Well, if a joyful event in this moment did not happen, then from 17 to 28 days the ability to fertilize is zero.

But it should be taken into account that all these calculations refer to the regular menstrual process. In case of its violation, any outcome is possible. Yes, plus the individuality of each woman, so it’s not worth relying completely on the proposed tables, since the reproductive system is a very cunning mechanism that can bring unexpected surprises, in a seemingly calculated to the smallest detail life situation.

Diagram of the menstrual cycle - menstruation and ovulation

To avoid disruptions in well-functioning work reproductive function, it is necessary that the phases of the menstrual cycle and the hormones that support them are in perfect harmony. Nature in this process thought through everything to the smallest detail.

If estrogen grows during the maturation of the egg, then progesterone has its minimum value. As soon as the first reaches its peak, the second immediately rises, taking its turn in the control of the following actions. Estrogen will not increase by the middle of the cycle, there will be no LH surge, ovulation will not occur, there will be no corpus luteum, there will be no one to produce the hormone of the second phase.

The slightest violation in this complex scheme of interaction leads to violations that prevent the conception and birth of a baby.

Most often, a negative effect on hormone function is exerted by external factors. Therefore, to keep your menstrual cycle running like clockwork:

• try to avoid stressful situations;
