" menstruation is the blood that is formed by the casting of the uterine epithelium prepared for pregnancy (if pregnancy does not occur) under the influence of the hormones produced in the ovaries after the stimulation of the high centers of the brain. If a more accurate definition of normal menstrual bleeding is needed, it can be suggested that this bleeding is the result of ovulation as well as the bleeding. "
As a result of the stimulation of the centers of the uterus, which is to carry the baby in the female organism, it is prepared so that a pregnancy occurs every month with the effect of the hormones produced by the ovaries. Usually an egg cell is taken out from the ovaries around the 14th day by describing the first day of menstruation as 1 day. If the egg cell captured by the ovarian ducts is fertilized by a sperm here, a pregnancy occurs. If the pregnancy occurs, the uterus undertakes the task of feeding and enlarging the baby. Without pregnancy, after the ovulation lasting 14 days, suddenly the blood levels are suddenly dropped out of the uterus with the effect of hormones falling. Blood comes to the fountain.
Periods of menstruation cycle

Follicular phase:
The effect of the estrogen hormone, which is the main hormone of the female organism and plays an important role in the emergence and maintenance of many aspects of the female body, multiplies the endometrial cells by mitosis, resulting in thickening of the endometrium. The follicular phase has a normal cycle of about 14 days. However, this period can vary considerably.
Ovulatuvar Phase:
The egg cells in the ovaries start functioning with orders from the High centers, and their interactions with the centers of the estrogen hormone are produced, resulting in the post-fertilization egg cell being thrown away.
Luteal Phase:
Spawning is the period when the effect of progesterone hormone emerging is dominant. It usually lasts 14 days and the secretion function in the endometrium is the frontal plane. A short period of 11 days can cause problems in terms of preventing gestation.
menarche:
It is the first menstrual bleeding in puberty. It is usually seen between the ages of 12-16. EARLY before age 8, LATE after age 16. In such cases, the underlying problem must be investigated. The age of menarche changes according to countries, races and even climatic conditions, and the first age is smaller than the previous centuries. Genetic factors, height and weight are closely affecting the first age. According to statistics, the average age of menarche was determined as 12.4 in our society.
Order:
It usually takes 28 days. The duration is from the beginning of one bleeding to the beginning of the other bleeding. It may be a symptom of a disease that is short in 21 days and long in 35 days. However, it is possible that menstrual bleeding may occur with longer intervals even in normal menstruation occasionally caused by ovulation.
Time:
It usually lasts 2 - 7 days. There are normal menstrual bleeding that lasts 1,5 days and rare menstrual bleeding that exceeds 7 days.
Quantity:
The amount of blood lost during one day of bleeding, about 2-3 pads per day of pad or cotton used, is 60-80 ml depending on the results of different investigations. with 50 - 150 ml. lt; / RTI & gt; In quite extensive research, this amount is about 40 ml. .
Characteristics of menstrual blood:
The most important feature is that it does not contain clots. Normally menstrual blood does not coagulate due to the substances in it that prevent the clotting. However, if the vagina lingers for a long time or if the bleeding is abrupt and abundant, then the clot may be free from the effects of the melting factors and clot.
