Is there any other reason besides pregnancy why my period hasn't arrived?

Patient's question:

No

Doctor's answer:

Generally, a delay of 3-7 days in the menstrual cycle is considered normal. Factors such as environmental changes, emotional fluctuations, and stress from study or work can all cause a delayed period. Some organic conditions may also lead to menstrual delays. It is recommended to relax, monitor closely, and if the period has not arrived after a week, consult a regular hospital for a six-sex hormone test to determine the cause.
