Perimenopause is a time of life when a woman’s body changes in preparation for menopause. However, it can be a lengthy transition and women aren’t considered to be in menopause until they have had 12 consecutive months without a period. It’s important to note that pregnancy is still possible during perimenopause; the potential for pregnancy only goes away after a woman has gone through menopause.
Women enter perimenopause at different ages. Typically, women will begin to notice symptoms in their 40s, but some may experience them sooner, some as early as their 30s. Perimenopause can last as short as two years or as long as 10 years.
