What is the effect of progesterone on the menstrual cycle - does it delay or advance menstruation?

Patient's question:

No

Doctor's answer:

Hello, generally a menstrual period that is one week early or late is considered normal. In the current situation, you can wait and see. If it still hasn't arrived after another week, you can take an early pregnancy test. If it's not pregnancy, it could be menstrual irregularity, and you can take Wuji Baifeng pills or herbal medicine to regulate it. If necessary, hormone-based artificial cycle treatment can be used.
