What is the cause of 44 days of amenorrhea?

Menstruation is now a normal physiological phenomenon for women that everyone knows. Moreover, modern society is no longer as conservative as before, and these private matters are no longer so private. The normal menstrual cycle is about 26-30 days, which means the average is about 28 days. Often women’s menstrual cycles are not so regular. Many women often experience menstrual disorders in their lives. What’s wrong with amenorrhea for 44 days?

The menstrual cycle refers to the menstrual period. Generally, a normal menstrual cycle is about 28 days. The method of calculating the menstrual cycle: starting from the first day of the previous menstrual period, the second menstrual period begins 28 days later. However, due to differences in physical constitution, age, climate, region and living conditions, the menstrual cycle may also vary. Anything within 7 days before or after 28 days is considered normal.

The menstrual cycle is essentially an external manifestation of the cyclical functional changes of the hypothalamus-pituitary-ovarian axis. Changes in the endometrium during each menstrual cycle can be divided into 3 stages.

1. The menstrual period lasts 4-5 days. As the levels of progesterone and estrogen in the blood drop to the lowest level, the prostaglandins produced by the uterus together cause the spiral arteries to spasm, thereby disrupting the blood supply to the endometrium. This will cause the endometrium and its blood vessels to necrotize and fall off, and the resulting bleeding can flush the dead endometrium into the uterine cavity. On the other hand, the increase in prostaglandins can also lead to contraction of the uterine muscle layer, which can cause dysmenorrhea that accompanies menstruation.

2. The proliferative phase (also called the follicular phase in terms of ovarian changes) lasts about 10 days, which is around the 5th to 14th day of the menstrual cycle. During this period, as the follicles grow, they secrete more and more estrogen, which gradually increases the estrogen level in the blood, thereby repairing the endometrium. As a result, the intima gradually grows and thickens.

3. The secretory phase is also called the luteal phase in terms of ovarian changes. It lasts about 14 days, that is, the 15th to 28th day of the menstrual cycle. This period is the result of the progesterone secreted by the mature follicle that forms a corpus luteum after ovulation at the end of the previous period, which acts on the endometrium.

Therefore, we can know that if a young woman of childbearing age suddenly stops menstruating and has had sex with her partner, she should first consider the possibility of pregnancy. However, in fact, on the other hand, when women are under great stress in life, it may cause delayed menstruation or even temporary amenorrhea, which requires our female friends to pay close attention. Go for B-ultrasound examination and blood hcg test in time.
