Are irregular periods a sign of perimenopause?

In perimenopause, which is the time before menopause begins, your body makes less estrogen and other hormones change. This process usually begins around 45 years of age. These shifts can cause your menstrual cycle to become less regular. You might find that your periods are longer, shorter, heavier, or lighter than before. Some months you might have a period, and other months you might miss one. While in perimenopause, you are still fertile, and missed periods should encourage a pregnancy test if sexually active. These changes are common in perimenopause and are part of your body adjusting to a new phase in life. Other signs you might notice include hot flashes, sleep troubles, and mood changes, although each person's experience is different.
