Can you get your period at 8 years old?

In general, it's extremely rare for a girl to get her period at 8 years old. On average, the human female body begins puberty and gets its first menstrual period around the age of 12 to 15, although this can vary from person to person. In exceptionally rare cases, a girl might start puberty much earlier, a condition called precocious puberty. However, starting menstruation at a very young age is highly unusual and should be discussed with a healthcare professional.
