The menstruation cycle is the period from one menstruation to another. To calculate its duration you need to know the first day of the previous menstruation and the first day of the next. The norm of the cycle duration for each woman is different, however, quite within the norm call the term 23-35 days.
Duration of the cycle - not the most important for a healthy female body, regularity is important. In addition, the duration of the menstrual cycle should not change - maximum deviations of 3 days are possible. Irregularities or other abnormalities should prompt you to see a doctor immediately.
Pregnancy directly depends on the menstrual cycle. Regularity promotes rapid conception. But if the menstrual cycle is broken, then there is no problem with pregnancy.
The menstrual cycle normally lasts 28 days and is divided into two phases. During the first phase, 14 days of the cycle, the body prepares for a possible pregnancy. Under the influence of follicle-stimulating hormone in one of the ovaries grows an egg. Then, another female hormone, estrogen, is secreted into the bloodstream. Which in turn makes a woman active and cheerful. It is important to note that while the body temperature is normal.
At the beginning of the second phase of the cycle, approximately two weeks later, the body is ovulating - this is the release of the ovum from the ovary. During this period, the temperature of the body does not rise much. After the release of the egg, it begins to move slowly along the fallopian tube. If a sperm meets on her way, fertilization will occur.
In the second phase, there is some swelling of the mammary glands. The main hormone of this half of the cycle is progesterone. If the egg was fertilized, then the second phase of the menstrual cycle is the beginning of pregnancy. If not, then the level of hormones in the body drops sharply and after a few days a new menstrual cycle begins. With a decrease in hormones, the unfertilized egg is approaching the exit and then there is a small blood loss - menstruation.
Menstrual cycles pass one after another, so continues until the woman becomes pregnant and becomes a mother. After the onset of the climacteric period, the female body loses the ability to have children, it is logical then menstruation ceases.
The constant management of her menstrual calendar helps a woman to determine the days when conception is possible. The other side of this - the knowledge of your cycle will help to avoid unwanted pregnancy.

Many disorders of the menstrual cycle are well treated with modern medications, the most important is to take care of one's own health.
