Irregular periods are one of the first signs of an approaching menopause.

Why Am I Having Irregular Periods?

Most women begin perimenopause in their late 40s or early 50s. The menopausal transition is different for everybody. Some go though it quite quickly with few or no symptoms, while others experience symptoms for years leading up to and following menopause.  During this time, women's bodies experience a hormonal imbalance which can lead to many of the common symptoms such as hot flashes, vaginal dryness, and irregular periods.

The fluctuating levels of the reproductive hormones estrogen, progesterone, and testosterone disrupt the menstrual cycle. This can cause infrequent periods, too frequent periods, heavy or light blood flow, longer periods, and painful cramping.

If I Am Menopausal Should I Be Experiencing Other Symptoms?

You should not be surprised if you experience irregular periods when you are 40 because they are extremely common at this age. However, having irregular periods doesn't necessarily signify that you will experience any of the other menopausal symptoms. Not all women experience symptoms, and not all suffer from them during the entire menopausal transition. So, it is possible for you to have irregular periods at 40 and not experience any other signs and symptoms of menopause.
