The rarest age to get your period is before the age of 9 or after the age of 15.
Most girls start their periods between the ages of 10 and 15. However, there are some cases where girls may start their periods earlier or later.
Early menarche (starting your period before age 9) can be caused by several factors, including:
- Family history: If a girl's mother or sisters started their periods early, she is more likely to do so as well.
- Obesity: Girls who are overweight or obese may start their periods earlier.
- Certain medical conditions: Some medical conditions, such as hypothyroidism, can cause early menarche.
Late menarche (starting your period after age 15) can also be caused by several factors, including:
- Low body weight: Girls who are underweight may start their periods later.
- Certain medical conditions: Some medical conditions, such as anorexia nervosa or Turner syndrome, can cause late menarche.
- Delayed puberty: This is a condition where puberty starts later than expected.
It's important to note that these are just some of the possible causes of early or late menarche. If you are concerned about your daughter's period, it's best to talk to her doctor.
