What could be the reason for my menstrual period not stopping after a week?

A normal menstrual period typically lasts 2 to 8 days, with an average of 4 to 6 days. If menstruation continues for a full week without stopping, there may be an underlying abnormality. It is advisable to visit a hospital for an ultrasound examination to check for any issues with the endometrium. Clinically, endometrial polyps are quite common; they result from localized excessive growth of the endometrial tissue. These polyps can be solitary or multiple, ranging in diameter from several millimeters to several centimeters, and can be classified as either sessile or pedunculated. Common features of endometrial polyps include intermenstrual bleeding, menorrhagia, prolonged menstrual periods, or irregular uterine bleeding.
