Fact Check: Are periods lasting over 3 days actually abnormal?
According to Dr. Anita Gupta, typical menstrual bleeding lasts 3 -7 days. Sudden changes in duration may indicate underlying hormonal imbalance, gynaecological disorders, or systemic conditions. The American College of Obstetricians notes that periods exceeding 7 days, irregular cycles, or unusually heavy flow require medical evaluation to rule out endometrial, thyroid, bleeding disorders.
