What is a normal menstrual cycle?

　　For most people, after ovulating these 400 eggs, they enter anovulatory menstruation. menopause , menopause is such a period. So we assume that under the premise of normal ovulation and menstruation, about 400 eggs are released in a lifetime, and the estrogen level is also normal, then menstruation can be delayed by 7 days in a month, and aging can be delayed by nearly 10 years in a lifetime.

What makes a woman's menstrual cycle normal? Many people believe that if it exceeds the normal cycle range, that is, 25-30 days, it is an abnormal physiological phenomenon. In fact, it is not the case. Whether menstruation is normal or not is not as simple as it seems on the surface. Some people have reached "seasonal menstruation", but it does not mean that they are not menstruating. healthy , in fact, this is closely related to the estrogen level and ovarian function in our body.
　　
Don’t be afraid if it grows any longer

The normal menstrual cycle is 25-30 days, and it is normal to be within one week early or late. However, some women's menstrual cycle may be delayed to two months or even longer, such as one quarter, which is the so-called "quarter menstruation" in medicine.

Even so, it does not mean that you are less healthy than others. If the estrogen level in the body is normal and ovulation is normal (the normal situation is that the left or right ovary releases an egg 12 days before the next menstruation), then this will not affect normal fertility and is a normal physiological phenomenon.

Estrogen is the most basic and dominant factor in women’s physiological health. From menarche to menopause, estrogen dominates for nearly 40 years. female menstrual cycle. Estrogen is a female hormone secreted by the ovary. Its quantity is very small. Together with progesterone and androgen, it controls the normal operation of menstruation through the three-level structure of hypothalamus-pituitary-gonads. The stability of estrogen secretion is the fundamental factor that determines whether menstruation is normal, rather than relying on the superficial "how many days once" to reflect it. Therefore, women with long menstrual cycles do not need to be afraid. As long as the balance and coordination of endocrine can be ensured, there is no need to be afraid of longer menstrual cycles.
