Potential Complications:
Blighted Ovum
Compiled by The Cradle Staff
hat is a blighted ovum?
Representing nearly half of all first trimester miscarriages, a blighted ovum or "anembryonic pregnancy" occurs when a fertilized egg implants itself in the uterine wall but does not continue to grow.
What causes it?
Most often, a blighted ovum is the result of a chromosomal abnormality.
How will I know if I have a blighted ovum? What happens?
Since this condition happens so early in pregnancy, you might not even be aware that you are pregnant. Otherwise, if you know that you are pregnant, an ultrasound will show evidence of the blighted ovum (by either an empty gestational sac or empty womb).
Or, you might only notice the problem once your body has naturally miscarried.
Symptoms could include:
- Vaginal spotting or bleeding (could appear as a heavy period)
- Minor abdominal cramps
Usually, your body can differentiate between normal and abnormal genetic material, and naturally miscarries since it cannot develop a pregnancy that is not viable. Sometimes, a D&C is performed if the tissue needs to be examined.
Can I prevent this from happening in the future?
While it is rare to experience a blighted ovum more than once, if you have experienced multiple losses in early pregnancy, consider genetic testing and possible fertility options.
As with any pregnancy loss, don’t be afraid to lean on others (loved ones or professionals) for support. And check out our article, Coping with a Loss.
