When does perimenopause start?

Women normally go through perimenopause between ages 45 and 55, but some women start perimenopause earlier, even in their 30s. When perimenopause starts, and how long it lasts varies from woman to women. The first menopause-related symptom you will notice is usually a change in your periods.
