Continuous Menstrual bleed for a Month??

Patient: Hi i have had my period for the whole month of march , some light days and some clotting , what could be the cause of this

Doctor: Uterine bleeding at irregular intervals, particularly between the expected menstrual periods is known as metrorrhagia. T his may be a sign of an underlying disorder, such as hormonal imbalance, endometriosis, uterine fibroids or rarely cancer. Long term metrorrhagia can cause severe anemia and needs to be evaluated by your doctor. I wish you well, take care.
