what is common age for menarche in girls
Girls experience menarche at different ages. It may not be the same as your friend. However, there is a range for most girls, which is about 11 to 14 years. A few girls may have menarche as early as age 9 or as late as the age of 15. Nevertheless, it should not be too early or too late. In general, you should see your doctor if you have your first menses before 9 or have not yet had any menses by 15 years.
