Why do women have menstruation?
After a normal woman’s ovaries and uterus mature, the ovaries regularly ovulate and secrete hormones. The uterus is affected by hormones, and the endometrium thickens and stores some Nutrients. When the released egg is fertilized, it travels through the fallopian tube to the uterus and stays in the uterus, where it develops into a fetus. This is the beginning of pregnancy.
If a female egg is not fertilized, it will die within 24 hours. About 2 weeks after ovulation, the endometrium sheds and bleeds, causing menstruation. When the next egg develops, the endometrium thickens. If the egg released is not fertilized, bleeding occurs again, and this happens repeatedly. Since ovulation occurs approximately once a month, uterine bleeding occurs once a month, so it is called \”menstruation\”. If an egg is ovulated every 25 days or 40 days, then menstruation will be every 25 days or 40 days. For some people, menstruation will be every 3 months or 6 months. As long as menstruation is regular, it is within the normal range. However, if there is a big difference between the two menstrual cycles, it means irregular menstruation, which is an abnormal phenomenon and affects pregnancy. You should consult a doctor for diagnosis and treatment.
At what age is it normal for women to have menstruation?
The morning and evening of menarche are related to economic level and nutritional status, as well as climate, health status, Genetic and social environmental influences. Recent surveys show that the age of menarche tends to be earlier. In my country, the age of menarche can be as early as 11 to 12 years old, and as late as 17 to 18 years old, but most of them are between 13 and 15 years old. . Urban and southern women have menarche earlier than rural and northern women. Therefore, it is generally considered normal to start menstruation between the ages of 11 and 18.
When a girl gets her period, it means that her eggs are mature and ready for fertilization to lead to pregnancy. However, menstruation does not mean that it is suitable for pregnancy, because women\’s physical development is not fully mature. If they become pregnant too early, it will be detrimental to themselves and the next generation. Menstruation in a woman can only mean that a woman has entered a new stage of growth and is gradually developing towards maturity. Generally, she becomes more mature after the age of 20.
Women who have early or late menstruation should be treated early.
Some girls have menstruation before they are 8 years old, and some have not had menstruation at 18 years old. What is this What\’s the reason? Most of these situations are abnormal, and you should go to the hospital for examination and receive appropriate treatment under the guidance of a doctor.
When girls before 8 years old have menstruation, they should also pay attention to other abnormal vaginal bleeding. Differentiate between them. For example, you mistakenly take your mother\’s birth control pill as a candy tablet, causing vaginal bleeding after stopping the pill; foreign objects inserted into the vagina cause puncture wounds or inflammation, causing bleeding; and some bleeding caused by tumors in the vagina or uterus, which is not menstruation. It is vaginal bleeding caused by other reasons.
If you do not have menstruation by the age of 18, if it is combined with breast dysplasia or short stature, you must check and analyze the reasons from all aspects related to menstruation. For example, whether the uterus is developing Normal, whether the ovarian function is complete, etc.
No ovaries, ovarian dysplasia, ovarian disease, or diseases that affect ovarian function, such as pituitary tumors, adrenal gland disease, long-term high fever, mental illness, etc. will all affect menstruation. Menstrual periods come on time. In addition, zinc deficiency can cause delayed puberty, and other chronic diseases outside the reproductive system, such as congenital heart disease, uremia, malnutrition, etc., can also delay puberty. These conditions should be checked and treated as soon as possible to avoid affecting fertility.
What is normal menstruation?

The menstrual cycle of most women is 28 to 30 days, and a few women have long or short menstrual cycles. The menstrual cycle of the same woman can also change due to various factors such as mental, physical strength, environment, disease, etc. , but the cycle is normal between 24 and 32 days (3 to 5 weeks). Some people have menstruation once every two months, but it is very regular and is normal.

(2) Menstrual period: Also called menstrual period, it is the time of bleeding. Usually menstrual period lasts for 3 to 5 days, and it is normal within 2 to 8 days. Start There is not much menstrual blood on the first day, then it increases in the next two days, and then gradually decreases until it is clear. Some people have menstruation and their blood is clear after three or four days, and then it comes again after one or two days. It is not a disease, it is a normal phenomenon, commonly known as menstruation. \”Look back\”. However, if the menstrual period lasts for 10 days or even 20 days without dripping,Menstruation is over, or the menstrual period is too short and just passes by in a \”flash\”. Both cases are abnormal menstruation and should be consulted by a doctor.
(3) Menstrual blood volume: The amount of menstrual blood in women varies greatly from individual to individual. Bleeding during the entire menstrual period is 20 to 100 ml, with an average of 50 ml. The amount of bleeding is heavy on the second and third days of menstruation, and then gradually decreases. If you change menstrual paper 3 to 5 times a day, it is normal. Some people have excessive menstrual bleeding, and the menstrual paper quickly becomes soaked after changing, and the menstrual blood even flows down the legs. This is abnormal. Excessive menstrual blood for a long time is harmful to human health and can cause anemia. Anemia is not good for pregnancy. You should go to the hospital for treatment. You can get pregnant only after you are cured.
(4) Menstrual blood color:Menstrual blood is mixed with small fragments of shed endometrium, cervix Mucus and vaginal epithelial cells do not coagulate, have no blood clots, and are dark red in color under normal circumstances. If the menstrual blood is completely clotted; or is as thin as water and only a little pink in color; or is black or purple, these are not normal conditions and should be diagnosed and treated in time.
In short, before pregnancy, you must ensure normal menstruation. If there are any abnormalities, they should be treated before pregnancy. Well, this is good for conception.
