Irregular periods are one of the first indicators that you are approaching menopause. Most women will start to experience irregular periods anywhere between three and ten years before their periods stop completely.

This is due to hormone imbalances and fluctuations as menopause draws closer, usually in women aged 45 t0 55. It is very common to experience irregular periods during this time. In fact, only 10% of women reach menopause without any irregular periods. If you have any questions regarding menopause, be sure to check in with your gynaecologist.
