The menstrual cycle is divided into several phases, each of which has a certain number of days. Every woman's "own" individual length of the menstrual cycle, and thus the number of days of each phase also differ. To calculate the "safe" when fertility is minimal or, on the contrary, "dangerous" days gynecologists advise to keep a calendar of menstrual cycle by which you can identify all his days. From the day of the menstrual cycle is not only fertile woman's ability (ability to get pregnant), but her emotional state.
The phases of the menstrual cycle
The first day of the menstrual cycle is considered to be (relatively) the first day of menstruation. Ideally, the length of the menstrual cycle is 28 days.
The menstrual cycle is divided into four phases: follicular, ovulatory, and luteal desquamative.
Follicular phase
The beginning of the follicular (proliferative) phase is considered the first day of menstruation. The duration of the first phase of the menstrual cycle is dependent upon its length. The average (with 28-day menstrual cycle) follicular phase lasts fourteen days, but can range from 7 to 22 days. In the first phase of the cycle under the influence of pituitary follicle-stimulating hormone in the ovaries begin to produce estrogen, which ensure the growth and maturation of follicles among them the dominant (main) follicle from which the future will mature egg capable of fertilization. In the same phase in the endometrium of the uterus occur proliferative processes, it begins to grow and thicken.
In the first or second day of the menstrual cycle, a woman feels the aching pain in the abdomen
Abdominal pain: when to sound the alarm?
Possible headaches, dyspepsia and irritable
Irritability - you try to control my temper
.
Third-sixth day of the menstrual cycle is characterized by a stabilization of the mood and physical condition.
In the seventh, the eleventh day of the menstrual cycle a woman is in a good mood, happy life, makes plans for the future.
Ovulatory phase
Ovulatory phase lasts 36-48 hours and at 28-day menstrual cycle begins on day 14-15. In the ovulatory phase of the estrogen level reaches its peak, it stimulates the production of luteinizing hormone by the pituitary gland, which is under the influence of the dominant follicle ruptures and out into the abdominal cavity leaves mature egg, then the estrogen level begins to decrease gradually. During the ovulatory phase may appear small, in the form of one or two drops of blood on the underwear (ovulatory bleeding).
Ovulatory phase - this is the most favorable time for conception (the egg is viable for 24 hours).
In the twelfth to fifteenth days of the menstrual cycle, a woman unconsciously watching their appearance, becomes passionate (due to increased sexual desire), and more feminine. He feels well.
Luteal phase
Luteal or secretory phase of the value of a more or less constant and lasts on average (with 28-day cycle) 13-14 days (plus or minus two days). After breaking his main follicle wall and fallen down on this spot formed the corpus luteum, which produces progesterone
Progesterone - norm and pathology
. Luteal phase flows under the influence of the pituitary luteinizing hormone. Under the action of progesterone in the lining of the uterus occurring phenomenon secretory endometrium becomes swollen and loosened (preparation for implantation of a fertilized ovum).
From the eighteenth to the twenty-second day of the menstrual cycle, a woman feels great, there is a burst of energy.
In 23-28 days of the menstrual cycle in women begins premenstrual syndrome. It is capricious, irritable, prone to depression
Depression - a little more than a bad mood
and tearfulness. The mood is unstable and changes several times a day. There may be swelling in the face and legs, pain in the lower back, swelling and increased sensitivity of mammary glands.
Phase desquamation
Phase desquamation - a rejection of the functional layer of the endometrium, or menstruation. The first day of menstruation, ie the first day of the menstrual cycle.
