Changes in Your Menstrual Cycle
For many women the first, though often ignored sign is a change in the length of menstrual cycles. Your cycles could get longer, shorter, or you could notice some other change in the usual pattern. If you have been regular as clockwork since you were thirteen, you will probably be more likely to notice any change. If you have had irregular periods, this may not hit your radar until later. But since pregnancy is not out of the question, be sure to consider that possibility as well, and don’t just assume you are entering menopause if you miss a period.
