How to calculate the time of menstruation?

Menstruation comes at different times every month. Most people will menstruate at the end of the month, but some people will menstruate before the month. But this doesn't mean anything, because everyone's menstrual time is different, just like menstrual time, everyone's menstrual process time is different, so it doesn't mean anything. If menstruation is normal, then the period of menstruation is similar every month. So, how to calculate menstruation?

How to calculate the time of menstruation: Under the regulation of endocrine, the endometrium has undergone a reaction from hyperplasia to secretion, with periodic shedding and bleeding, which is one of the signs of the maturity of reproductive organs. In addition to blood, menstruation also includes endometrial debris, cervical mucus and exfoliated vaginal epithelial cells.

The age of menarche is about 1 1? 18 years old, mostly 13? 15 years old. The interval between two menses on the first day is menstrual cycle, which is generally 2 1? 35 days, with an average of 28 days. The duration of each menstrual period is menstrual period, generally 3? 7 days, menstrual flow 30? 50ml, menstrual flow exceeding 80ml is menorrhagia.

Menstrual blood is dark red, characterized by non-coagulation. Under normal circumstances, there should be small blood clots occasionally, and there are activating factors in the endometrium to activate plasminogen in the blood, which causes menstruation to be liquid and not coagulated.

Every healthy girl will have her period, which is a physiological phenomenon that we have known since childhood. So, when will this girl have her period? Because the physical condition and nutritional status of girls are different, the time of menstruation will be different.

When does the girl have her period?

Every girl's menarche time is different, so girls don't have to compare too much with others. When it's time to come, menstruation will come naturally and there is no need for psychological burden. Generally, the age of menarche is between13 and15 years old. Some of them have menarche age of 1 1 ~ 12 years old, and some have menarche age of 17 ~ 18 years old, which is influenced by many internal and external factors.

How often do women menstruate once a few days?

Menstrual blood is menstrual bleeding. Under normal circumstances, menstrual blood is slightly dark red, light at first, then gradually deepened, and finally turned pale red until it is clean. If the color of menstrual blood is always bright red, purple or light yellow, brown, etc. It belongs to abnormal menstrual blood color. Whether menstruation is normal or not depends on the characteristics of menstrual blood. Under normal circumstances, menstrual quality is not thin or thick, not easy to solidify, and there is no obvious blood clot or special smell. If menstrual blood is thick or thin like water, sometimes there may be more blood clots, so we should pay attention to whether there is anemia or uterine fibroids.

Women's menstruation usually lasts for 3 ~ 5 days, but as long as it lasts for 2 ~ 7 days, it still belongs to normal menstruation. If the menstrual duration is too long or too short, it is recommended to go to the hospital to check whether there are uterine diseases or endocrine disorders. Of course, occasionally the menstrual period is too long or too short, which may be due to environmental and emotional influences. If this is the case for several months in a row, it is recommended to check whether there is any abnormality in the body.

The normal menstrual flow of women is 20 to 60 ml. Due to the influence of personal physique, age, climate, region and other factors, menstrual flow will also increase or decrease, which belongs to the normal physiological category. If the monthly menstrual flow is less than 50ml or more than 100ml, you should consider whether you have menstrual disease.
