What factors are affecting my period?


Many factors contribute to good reproductive health including a good diet, regular exercise, enough sleep, and manageable stress levels.

Age and BMI

A healthy Body Mass Index, i.e. weight to height ratio, is important for a healthy menstrual cycle. Very low and very high BMIs associated with eating disorders or malnutrition, are significant contributors to irregular periods.

Medical History

Past medical conditions, new course of drugs including antidepressants or contraceptives, and predisposition to genetic factors could all play a role in influencing your period.
