Is it normal to have periods months apart for 5 years?

Perimenopause: 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. In the last 1 to 2 years of perimenopause, this drop in estrogen speeds up. At this stage, many women have menopause symptoms including irregular periods or no periods, hot flashes, lower sex drive, fatigue.
