Blighted ovum is another form of early pregnancy loss. It is also known as an “anembryonic gestation.” This means that a baby or embryo never forms.
Chromosomal disorders of the egg, or ova, are thought to be the main cause of this type of loss. It is usually detected during an ultrasound where a gestational sac is seen with no yolk sac or embryo. You may miscarry normally. The pregnancy may reabsorb itself. Or surgery may be necessary to end this form of pregnancy.
