Leading up to your period, prostaglandin and progesterone levels rise. This has an effect on your body, such as feeling sick, bloating, cramps, diarrhoea, or constipation. There are things you can do through diet, supplements, and medication to help manage the symptoms. If it’s not affecting your everyday life then it’s just one of the natural and annoying things that we experience during our period. If, however, your bowel movements, sickness, or stomach cramps are affecting your day-to-day life then go and speak to your doctor to check there are no underlying health conditions.
