Introduction
It may be normal for a 13-year-old girl not to have started menstruation yet. The timing of a girl's first menstrual period is influenced by various factors. Generally, the age of menarche in girls ranges from 11 to 16 years. Genetic factors play an important role in determining the timing of menarche. If a girl's mother or other female relatives experienced late menarche, the girl may also tend to start menstruation relatively late.

Generally, it may be normal for a 13-year-old girl not to have started menstruation yet. However, if she experiences any discomfort, it is advisable to seek timely medical evaluation and receive standardized treatment under the guidance of a physician. The specific analysis is as follows:

The age at which girls experience their first menstrual period (menarche) is influenced by multiple factors. Typically, menarche occurs between the ages of 11 and 16. Genetic factors play a significant role in determining the timing of menarche. If a girl's mother or other female relatives experienced late menarche, the girl herself may also start menstruating relatively later. Nutritional status can also affect the timing of menarche. Prolonged malnutrition and delayed physical development may lead to a later onset of menstruation, whereas girls who are well-nourished and develop physically more quickly may experience menarche earlier. In addition, environmental conditions and psychological factors may also influence the timing of menarche. Girls living in high-stress environments or experiencing heavy psychological burdens may have delayed menarche.

It may be normal for a 13-year-old girl not to have started menstruation, but various factors should be comprehensively evaluated, and medical advice should be sought when necessary. Parents should pay attention to their daughter’s physical development, provide adequate nutrition, and ensure a healthy living environment to support her overall growth and well-being.
