How long first period lasts?

The average length of a first period is between 2 and 7 days. However, it is essential to remember that every person's menstrual cycle is unique, so the length of the first period can vary from person to person. Some people may experience a shorter first period, while others may have a longer one. Additionally, the length of a person's first period may not necessarily be indicative of the length of their future periods. Over time, the length of menstrual periods can fluctuate and may become more regular.
