Periods that last longer, appear more or less frequently, or are heavier or lighter
As levels of estrogen rise and fall irregularly through perimenopause, your menstrual cycles may lengthen or shorten, and you sometimes have menstrual cycles in which your ovaries don't release an egg. When this happens, there is no progesterone to stabilize the lining of the uterus. The uterine lining builds irregularly, leading to sporadic bleeding. When you then have a cycle during which an egg is released, you may experience a heavy, long period. Heavy bleeding can lead to other problems like anemia and fatigue
Sometimes a change in bleeding patterns (whether it be time in between or heaviness of flow) can be a sign of something more serious, so a visit with your OB/GYN is recommended.
