You are losing more or less blood during a period than usual.
The number of days that your period lasts varies.
There are different names for different types of irregular periods:
Oligomenorrhea refers to infrequent periods. The time between periods is typically 35 days or more. Women with oligomenorrhea have fewer than six to eight periods a year.
Metrorrhagia refers to irregular but frequent periods.
Menometrorrhagia refers to longer or heavier periods that are irregular but frequent.
Amenorrhea refers to an absence of periods for three to six months or longer.
Do Irregular Periods Need Treatment?
Treatment of irregular periods depends on the cause and your desire to have children in the future. Irregular periods can be caused by many different things. Changes in your body's level of the hormones estrogen and progesterone can disrupt the normal pattern of your period. That's why young girls going through puberty and women approaching menopause commonly have irregular periods.
