A Normal Part of Life
Perimenopause is the period leading up to actual menopause (when 12 months goes by and you haven’t had a period). Most women go through menopause between ages 45 and 55. On average, 52 is the age at which American women have their last menstrual
period. When perimenopause starts and how long it lasts varies. Perimenopause can start as early as age 35 and last a few months or several years.
During perimenopause, the levels of your reproductive hormones estrogen and progesterone rise and fall unevenly. Your menstrual cycles gradually lengthen, and you begin having menstrual cycles in which no ovulation takes place. Only during cycles with
ovulation is there a possibility for pregnancy to occur3.
As ovulation becomes more erratic and your body produces less progesterone, you may have longer and heavier periods. Other physical changes and symptoms common during perimenopause are due to reduced estrogen production.
Menopause, sometimes called "the change of life," marks the end of your reproductive years. When you have gone 12 months without a period, menopause is considered complete. Changes in bleeding are normal as you near menopause; however, any bleeding—even
spot bleeding— that you experience after menopause is not considered normal and could be a sign of a health problem. That’s why it is important to report any abnormal post—menopausal bleeding to your physician

The Menstrual Cycle
A Time for Change
During perimenopause, it is natural for periods to become more irregular and, therefore, less predicable. “Spotting” is also common as menopause grows near. Whereas in years past your period may have come like clockwork, you may find yourself
much more uncertain about when your period will arrive, how heavy or regular the blood flow will be—and where you will be when that protection is needed.
