Blighted Ovum: Causes and Coping
A blighted ovum, clinically called an anembryonic pregnancy, occurs when a fertilised egg implants and forms a gestational sac but the embryo does not develop. It is one of the most common causes of early miscarriage, yet many women have never heard of it before their scan. Understanding the causes can help relieve the self-blame that often accompanies this loss.

What Causes a Blighted Ovum
The vast majority of blighted ovums are caused by chromosomal abnormalities in the fertilised egg. The body recognises the problem early and stops embryonic development, while the gestational sac may continue to grow for a time, which is why pregnancy symptoms can persist. It is not caused by stress, exercise, sex, diet, or anything you did. The risk increases slightly with age, but it can happen to anyone at any age and having one does not increase the risk of another.
Coping Emotionally and Physically
A blighted ovum is a real pregnancy loss and your grief is valid, even if there was no embryo visible. Allow yourself time to process the news and avoid rushing decisions about management. Talk to your partner, friends, or a counsellor: the Miscarriage Association offers free support. Physically, recovery depends on your management choice, but most women's cycles return within four to six weeks. Most women go on to have a healthy pregnancy next time, and your GP can arrange follow-up if you have recurrent losses.
Frequently Asked Questions
1. Did I cause my blighted ovum?
No. It is almost always caused by a chromosomal issue in the embryo that is entirely beyond your control.
2. Will I have another blighted ovum?
Most women do not. Having one does not significantly increase your risk of another.
3. How long until my periods return?
Typically four to six weeks after the miscarriage is complete, though it can vary.
