What should I do if my menstrual cycle is very irregular?

Patient's question:

I have been menstruating for three or four years, but my period is very irregular—it's either too early or too late. Moreover, the duration of my period is usually quite long, lasting about a week or even longer. The first few days of my period seem relatively normal, but especially in the later days, the flow becomes lighter, and the period doesn't end until very late. What could be the reason for this?
First follow-up question: Does taking Ejiao (Chinese medicine) help regulate the menstrual cycle?

Doctor's answer:

This reason has many factors. Only through examination can it be determined. There are many causes of menstrual disorders, such as: common ones include abnormal ovarian function, uterine diseases, cavity diseases, endocrine dysfunction, gynecological inflammation, emotional fluctuations, drug effects, environmental changes, overexertion, and excessive mental stress, etc. It is recommended that you first rule out external factors affecting menstruation, and then wait for a while. In daily life, maintain a regular routine, pay attention to rest, avoid overexertion, especially during menstruation, to prevent cold and dampness. Avoid excessive dieting, smoking, and limit alcohol consumption. Pay attention to your dietary structure, consume more lean meat, grains, dark green leafy vegetables, and calcium-rich foods, and avoid overeating cold and raw foods. Maintain a cheerful mood, strengthen exercise, and improve physical fitness. If the symptoms do not improve, it is recommended to go to the hospital for examination to identify the cause and follow medical advice for early, targeted treatment.
