What is amenorrhea in teens?

Also known as: amenorrhea, absent menstrual periods.

Amenorrhea is defined as a girl not having a menstrual period for three monthly cycles or longer. Most girls get their periods two years after the start of breast development and certainly, by age 16. Amenorrhea may be “primary” (where menstruation never starts), or “secondary” (when periods have begun, but then stop).
