A young girl's menstruation hasn't arrived. What should I do?

Patient's question:

14-year-old girl, still bleeding after half a month's menstruation, not much bleeding, with viscous discharge

Doctor's answer:

It may be caused by irregular menstruation. Generally, methods such as dietary therapy, massage, and medication are used to help promote the normal development of follicles, improve physiological functions, and restore menstruation to its normal physiological pattern. During menstruation, it is important to keep warm, avoid catching a cold, not eat cold foods, not overexert oneself, maintain a cheerful mood, and balance work and rest.
