A molar pregnancy is one in which a healthy baby can't develop. Although easy to treat, this condition can be incredibly hard to face. We'll tell you what to expect.

In a molar pregnancy the fertilisation of the egg by the sperm goes wrong and creates abnormal cells or clusters of water filled sacs inside the womb. Molar pregnancies can be complete or partial.
