Period Irregularity: Our menstrual cycles r regulated by 2 main hormones estrogen &progesterone. These in turn are regulated by our internal body environment and our responses to our external environment. Stress of all sorts affects hormone balance thus having an impact on our bodily functions such as our periods. Stress can be anything from life changes, road rage to allergies to an infection to our eating habits.
