How should a 17-year-old girl deal with her period not coming for a month?

Patient's question:

No

Doctor's answer:

Hello, for a girl of this age, if her menstruation hasn't come for a month, it could be due to changes in physiological indicators or the influence of mental factors. Additionally, pay attention to whether it's due to endocrine disorders. If there's not a significant deviation, wait a few more days to see.
