What happens when a girl gets her period early?

I honestly dont wanna lie so i say look it up on google.com

Nothing

In the US the age of menarche (first period) has been getting earlier and earlier.

In 1860 the average age was 16.6 years. By 1920 it was down to 14.6, in 1950 it was down to 13.1 and in 1992 average was 12.2. Now it is probably between 10 and 11.

There are a number of theories why the age has been falling for over a century. Richer diets allows girls to mature earlier and our diet had been getting richer for a long time. An interesting thing is that in Japan when they ate their traditional diet the age of menarche was about 17 but now that most Japanese youth eat Western style diets it is almost as low as our own.

Early puberty isn’t considered a medical problem unless girls begin to show signs of puberty before 7 or 8 and before 9 for boys. Some problems associated with precocious puberty in girls are greater danger of hormone influenced cancers and since puberty begins the process of closing the growth plates in bones these kids may stop growing before they reach full stature.

yeah like depending on how old you are and when you first had your period a lot of girls dont start actually having a regular period for quite a while so it really means nothing that i know of…..

yeah just probably irregularr. My periods are irregular. SOme months i get them really early or very late.
