1, the menstrual cycle.Woman's menstrual cycle is usually 28-30 days, but it was also to a period of 30 days, it was even 40 to the first period. As long as there is regularity, which is roughly the same menstrual cycle the first time, all is normal. In addition, the menstrual easily affected by many factors, so after 3-5 days in advance or wrong, is normal. If the menstrual cycle is 20 days, the next 40 days, separated by the number of days a lot, and often appears to be the case that, or even 1-2 days of menstruation, after 10 days again for 1-2 days, lost cyclical, which is not normal, called irregular menstruation. It should be noted, girls menarche, due to ovarian just the development, function is not perfect, so there will be disorder, not the law, this is not a pathological phenomenon, not fear and anxieties, over a year or two ovarian maturation, menstruation fate to normal.

Calculated according to the menstrual cycle, ovulation method, also known as the calendar method. Menstruation and ovulation are subject to the pituitary and ovarian hormone showed the impact of cyclical changes in cycle length between the two is the same, is a monthly cycle, ovulation occurs in the middle two periods.

2, the menstrual period (also known as menstruation.)Woman's menstruation is about 3-5 days, 2-8-day are not uncommon. The first day of the general law of passing much blood, and the second, three days more, and then gradually decreased until the blood clean. This is because the first day of the endometrium has just begun, and the second, three-day increase in endometrial shedding, also increased the amount of bleeding, uterine stimulation, strengthening the contraction of the reason a large amount of blood discharge. Some people clean blood after a little over a day or two again, like "the blood back", this is not the disease, but a normal phenomenon. However, some women's menstrual period up to 10 days, or even 20 days, endless dripping menstruation; some very short period, only "flash" that is over. These two phenomena are not normal.

3, by the blood.Vary the amount of menstrual women, individual differences, typically 20-100 ml, an average of about 50. 3-5 times a day for normal menstrual sanitary napkin or paper, even if it is normal. If by the blood too much, change a sanitary napkin or paper quickly and soaked through, and even blood drip down along the thigh, which is not normal. Menorrhagia, may be psychological stress, environmental changes, malnutrition, and metabolic disorders caused by factors such as dysfunctional uterine bleeding. Anemia caused by excessive blood long-term, it should be immediate early medical treatment, identify the reasons for treatment. Of course, it may be due to the uterus, ovaries are not normal or systemic disease, caused by menstruation is too small, this situation is not normal to timely medical treatment. Adolescent girls with menstrual flow into the more common and more. The main reason is in puberty, ovarian function is still indicated full maturity, a part of this time period are anovulatory in nature. There is no ovulation there is no corpus luteum, there is no corpus luteum to the lack of progesterone. Therefore, in the proliferative endometrium and not only to improve the secretory phase, resulting in incomplete endometrial shedding of uterine contractions, resulting in excessive menstrual flow. If we do not draw attention to this situation, over time, can appear pale, fatigue, dizziness and other symptoms of anemia, should medical treatment.

4 blood color.Normal blood is dark red blood mixed with spit off a small piece of endometrial, cervical mucus, vaginal epithelial cells, blood is not frozen, so no blood clot.
