What are the reasons for a delay of more than twenty days in menstruation?

Patient's question:

No

Doctor's answer:

Hello, if you can completely rule out pregnancy, then it could be caused by endocrine disorders leading to menstrual irregularities. You can take Wuji Baifeng Pill to regulate the endocrine system. If it still hasn't arrived, you will need to use progesterone to regulate your period. Generally, progesterone can be taken for 5 days, and after stopping the medication, your period should come within 3 to 7 days.
