The first phase is the first day of monthly ones.
Ovulation phase. Under the action of follicle-stimulating hormone, there is an increase in follicle, which lasts until ovulation. Once the follicle reaches the necessary size and functional activity, the concentration of the hormone increases, which helps the maturation of the egg cell. Once the maturation process ends, a rupture forms in the follicle and the oocyte exits outward.
The final phase is the first day of the next menstruation.
Twenty-eight calendar days are considered to be an ideal cycle duration, but this figure can fluctuate depending on the state of the organism. Family couples planning a child need to know that conception is most likely during the period of ovulation.

The beginning of the cycle can be calculated by measuring basal temperature. During the period of ovulation there is a temperature rise from 0.5oC to 0.7oC. This temperature is held until the start of pregnancy and until the end of the cycle. The basal temperature is measured in the morning, after waking up. It can be measured in the mouth, in the vagina, or in the rectum. The obtained data is written to a notebook. Adds twelve — sixteen days to the start date of ovulation and get the start day of the next monthly ones.
In the period before the cycle, a woman may experience changes in the body. Feel the swelling of the chest glands, pulling pains at the bottom of the abdomen and back. Also during this period, sensitivity increases and irritability increases. All of these changes are called premenstrual syndrome, after the onset of which menstruation begins within three to four days.
If the menstrual cycle is inconstant, diseased or accompanied by abundant blood secretions, it is necessary to contact a specialist to diagnose the condition, as cycle failures are symptoms of endocrine or gynecological diseases in women.$ Timely anxiety and going to the doctor will help prevent the negative effects of a possible infection.
