How long does a woman have periods?

Women usually have periods until menopause. Menopause occurs between the ages of 45 and 55, usually around age 51. Menopause means that a woman is no longer ovulating (producing eggs) and can no longer get pregnant. Like menstruation, menopause can vary from woman to woman and these changes may take several years to occur. The time when your body begins its move into menopause is called the menopausal transition or Perimenopause. This can last anywhere from two to eight years. Some women have early menopause because of surgery or other treatment, illness, or other reasons. If a woman doesn’t have a period for 90 days, she should see her doctor to check for pregnancy, early menopause, or other medical problems that can cause periods to stop or become irregular.
