A 10-year-old girl shows signs of puberty, inquiring about the possibility of using medication to delay her menstrual cycle. The doctor advises to pay attention to diet and undergo examinations. If diagnosed with puberty precocity, medications such as Diphereline and Estracon can be used for treatment.

My daughter is 9 years and 9 months old, with a height of 1.34 meters and already has vaginal discharge. Is she short for her age, suffering from puberty precocity, and does she need treatment?
