What is the problem when menstruation is abnormal?

Patient's question:

Duration of onset and persistence: 4 months
Current general condition: Menstruation is very infrequent
Medical history: I had an induced abortion last year
Detailed condition and consultation purpose: Since having an induced abortion last year, my menstruation has been abnormal, and the amount is very small. In the later days, the color turned brown. Am I suffering from some disease?

Doctor's answer:

Hello; As you mentioned, in this case, menstruation being or by no more than 7 days is considered normal. After ruling out pregnancy, multiple reasons can cause menstrual delay. If there is stress, high psychological pressure, environmental changes, etc., if menstruation does not arrive after being delayed for more than 10 days, hormones such as progesterone can be used for treatment. It can also be regulated through traditional Chinese medicine's method of observation, listening, inquiry, and palpation for syndrome differentiation and treatment. If necessary, it is recommended to go to a regular hospital's gynecology department for systematic examinations such as ultrasound of the uterine appendages to determine the cause.
