Hormone levels: As we enter our 40's, our hormone levels can fluctuate more. Estrogen and Progesterone control our cycle and they can become more erratic. Thyroid levels can affect cycles as well. Excess weight or excess thinness can cause changes too. If you're concerned i would see a physician so that they can get a complete history and possibly run some tests.
