Perimenopause, or menopause transition, begins several years before menopause. It's the time when the ovaries gradually begin to make less estrogen. It usually starts in a woman's 40s, but can start in her 30s or even earlier. Perimenopause lasts up until menopause, the point when the ovaries stop releasing eggs. In the last 1 to 2 years of perimenopause, this drop in estrogen speeds up. At this stage, many women have menopause symptoms.
Two sub-stages of perimenopause. Early perimenopause is marked by increased variability in menstrual cycle length. Your cycles may shorten to 24 to 27 days instead of 28 to 31, and your periods might be heavier or lighter than they used to be. Your FSH levels will rise. You will experience menopause symptoms increasingly.
