Absence of Menstrual Periods
There are two main types of amenorrhea: Primary:Menstrual periods never start. Secondary:Periods start, then stop. Usually if periods never start, girls do not go through puberty, and thus secondary sexual characteristics, such as breasts and pubic hair, do not develop normally. If women have been having menstrual periods, which then stop, they may have secondary amenorrhea. Secondary amenorrhea is much more common than primary.
