Typically, the menstrual cycle is 28 days. Allowable movements are considered to be within 21-35 days. Its duration may change under the influence of various factors.
The menstrual cycle leads to certain changes in the ovaries of women, which are usually divided into phases such as follicular, ovulatory and luteal. The first day of menstruation is considered the beginning of the cycle, and the day before the beginning of the next menstruation - the final day.
Let us examine the phases of the menstrual cycle in more detail by day.
The follicular phase
The duration of the first phase of menstruation is, on average, 14 days. The first 4-5 days is the time of menstruation. Then the body begins to prepare for a possible pregnancy. Increases the production of estrogen, which promotes the growth of follicles and affects the maturation of the egg. The growth of a new layer of epithelium begins, and the preparation of the uterus for the implantation of a new egg.
This phase in the early days is characterized by soreness, irritability and pain in the lower abdomen. Then the state gradually stabilizes.
Ovulatory phase
It starts on the 14th - 15th day of the cycle. Among the three phases of the female cycle is the shortest by the day - about three days. The body of a woman synthesizes the largest number of estrogen. The follicles burst, and the egg leaves the abdominal cavity with further movement into the orifice of the fallopian tube. The life of the egg is small - only 24 hours. But this time is the most suitable for planning a pregnancy.
To precisely determine on which day of the cycle the ovulatory phase has begun, the measurement of the basal body temperature will help. These days it is elevated.
Luteal phase
This is the time between ovulation and the onset of a new menstruation, or pregnancy. Some women do not know on what day the beginning of the luteal phase of the cycle enters.
During this period, the uterus is preparing to take an egg. When fertilization occurs - the egg is fixed in the uterine cavity. Otherwise, there is a gradual rejection of the outer layer of the endometrium and a new cycle begins.
The menstrual cycle is a delicate and complex mechanism, from the successful work of which the woman's reproductive health depends. Knowledge of the phases of the menstrual cycle on days will allow you to understand your body more and in accordance with it build your plans.
