Summary
Background: Most adult women with irregular periods of unknown cause report symptoms dating back to early adolescence. This study aims to learn how girls' periods change in the 2 years after their first period. We are also looking at girls who may have a condition called PCOS. This will help researchers learn what healthy puberty looks like and how they can spot signs of hormone problems early on.
