It usually takes a few days for menstruation to be completely clean

Menstruation usually takes 3-7 days to be completely clear. The specific time varies from person to person and is related to factors such as hormone levels and endometrial thickness.

The duration of menstruation is affected by many factors. A healthy woman's menstrual period usually lasts 3-5 days, but may extend to 7 days in some people. Bleeding is heavier at the beginning of menstruation, then gradually decreases, and finally ends with a small amount of brown discharge. The speed of endometrial shedding and changes in prostaglandin levels will affect the length of menstrual periods. Life stress and mood swings may prolong menstruation through neuroendocrine regulation. Excessive dieting or obesity may interfere with hormone secretion and lead to abnormal menstruation. Uterine fibroids, endometrial polyps and other organic diseases may cause the menstrual period to be prolonged for more than 7 days. Endocrine diseases such as polycystic ovary syndrome are often accompanied by menstrual cycle disorders.

It is recommended to record the menstrual cycle and the number of menstrual days, use breathable sanitary napkins and change them regularly. Avoid strenuous exercise and bathing during menstruation, keep the abdomen warm, eat a light and warm diet, and supplement iron-containing foods such as animal liver, spinach, etc. If your menstrual period exceeds 10 days, excessive menstrual bleeding or severe dysmenorrhea, you should seek medical examination in time to rule out the possibility of organic diseases. Maintaining a regular daily routine and moderate exercise can help maintain a normal menstrual cycle.
