Why does my period come a few days earlier every month?

Menstruation coming a few days early every month may be a normal condition or a pathological condition. Under normal circumstances, it is normal to arrive 3-5 days earlier or later. However, if the menstrual period is often advanced, for example, more than a week early each time, then the menstrual cycle will be shorter than 21 days. In this case, it is likely that the corpus luteum function is insufficient. Insufficient corpus luteum function can easily cause infertility or symptoms of miscarriage during pregnancy. In this case, you can try estrogen (corpus luteum copper) supplementation in the first half of the menstrual period.

It is normal for menstruation to come 5 days early every month. Because in a normal menstrual cycle, it is normal for menstruation to come a week earlier or later. In many cases, the menstrual cycle will fluctuate due to the influence of mental and emotional stress. Menstruation comes 5 days earlier every month, and the ovulation period of women is still in the middle of two menstruations. If there is no pregnancy, the corpus luteum will begin to shrink 9 to 11 days after ovulation. The follicular phase of the uterus and ovaries is generally 14 days, and in most cases it will not change.

If your menstrual period comes earlier every month, your menstrual cycle will be shortened. As we age, our menstrual cycles become shorter, which is caused by the gradual decrease in the reserve function of the uterus and ovaries. As we age, the reserve function of the uterus and ovaries is poor, the inhibitory hormone in the metabolism of the granulosa cells of the eggs decreases, and when we reach the late lutein phase, the eggs begin to grow and develop very early. That way the follicular phase is reduced. Generally speaking, the follicular phase lasts for 14-2 days and is fixed. Therefore, the length of the menstrual cycle generally depends mainly on the length of the follicular phase. Therefore, a reduction in the follicular phase means a decrease in the reserve function of the uterus and ovaries.

If your period comes within 7 days of your last menstrual period, it is considered normal, as the menstrual cycle varies to some extent due to factors such as diet, mood, exercise, and environment. If the menstrual period comes more than 7 days earlier or even more than 10 days earlier every month, it is considered to be early menstruation, which is mainly related to Qi deficiency and blood heat. If you are physically weak, work too much, worry too much, have an irregular diet or have too much sex, or suffer from long-term illness and damage your yang, the Chong and Ren meridians may not be nourished and menstruation may not be controlled, so your period comes early. Or the emotions are hurt, which turn into heat, or there is heat evil, which disturbs the Chong and Ren meridians and forces blood to flow abnormally, so menstruation comes early.
