A uterus is usually pear-shaped and is in a straight vertical position. Many different abnormalities can occur in the shape and position of your uterus. Some of these are minor, like a tilted uterus, and don’t impact fertility, pregnancy, and birth. Some abnormalities are more severe and may increase your risks for complications. It is estimated that 4-7% of women have some abnormality when their reproductive system is formed. One of those anomalies is a bicornuate uterus, commonly referred to as a heart-shaped uterus. This episode explains a tilted uterus and a heart-shaped uterus and the risks for you and your baby.
