Symptoms of perimenopause that begin with P are:
Period changes - missed period; shorter, lighter periods; heavier periods, flooding;
shorter cycles, longer cycles
Perimenopause brings about hormone imbalance, or a decrease in estrogen. Your hormones affect your period in a variety of ways. They may come later than usual, they may be lighter than normal or last a shorter amount of time. At other times your period may be very heavy and last much longer. You may have a missed period one month, then go back to normal for several months, then miss two periods. Missed periods increase as perimenopause develops into menopause.
