Uterous

The uterus has three major functions: to prepare a bed for a fertilized ovum, to nourish the developing embryo during pregnancy, and to expel the fetus. Shaped like an upside-down pear, and tilted forwards, it lies within the pelvis and is held in place, along with its two extensions, the Fallopian tubes, by ligaments and folds of the peritoneum. The cervix forms the lower third, connected by a narrow isthmus to the main muscular body of the uterus. The non-pregnant uterus weighs 45–60 g and is 7–8 cm long but its weight increases more than ten-fold by the end of pregnancy.

Prolonged menstrual period

Prolonged menstrual bleeding is bleeding that continues for more than 7 days. Also known as menorrhagia, prolonged menstrual bleeding can be caused by structural problems within the uterus, hormonal imbalances or problems outside the reproductive tract, such as the use of certain medications or inherited bleeding disorders.
