What tests should be done if you have three menstrual periods in a month?

Patient's question:

Three times a month for a month, very little amount, color is black, what check should be done

Doctor's answer:

Hello, this situation should be caused by endocrine disorders leading to menstrual irregularities. You can try traditional Chinese medicine such as Yimucao Granules, Qixue He Capsules, or Wuji Baifeng Pills to regulate it. If necessary, you can also try progesterone injections. Pay attention to maintaining a balanced diet and hygiene.
The occurrence of menstrual disorders not only affects the patient's physical health but can also lead to gynecological diseases. Therefore, it is best to visit the gynecology department of a hospital for a vaginal examination to identify the cause and receive targeted treatment. Additionally, pay close attention to personal hygiene and keep the perineal skin clean.
