Blighted Ovum and Missed Miscarriage: What They Mean and What Comes Next

Few moments in early pregnancy are as hard as a scan that shows something is wrong, especially when you felt nothing, saw no bleeding and had every reason to hope. A blighted ovum and a missed miscarriage are two ways this can happen. They are also very often misunderstood, and many women quietly blame themselves. This article explains what these terms mean, why they happen, how doctors manage them, and how to look after yourself afterwards.

The Short Answer

What to Know A blighted ovum and a missed miscarriage are both early pregnancy losses that are found on a scan, often before any symptoms. They are most often caused by chromosomal problems in the embryo, not by anything you did. You are not at fault, and there are safe ways to manage it with your doctor.

What Is a Blighted Ovum?

A blighted ovum, also called an anembryonic pregnancy, happens when a fertilised egg implants in the womb and a pregnancy sac forms, but the embryo itself does not develop, or stops developing very early. The sac may keep growing for a short while, and the body may keep producing pregnancy hormones. That is why a home pregnancy test can still look positive and you can still feel pregnant.

On a scan, the doctor sees an empty sac with no embryo inside. It is not a "bad egg" in any way you could have prevented, and it does not mean there was something wrong with your body.

What Is a Missed Miscarriage?

A missed miscarriage, sometimes called a silent miscarriage, is when an embryo has stopped developing but the body has not yet passed the pregnancy tissue. You may have had no pain or bleeding, and may have felt pregnant right up to the scan. It is called missed because the loss was missed by your body's usual signals.

The two terms overlap. In a blighted ovum, an embryo never developed properly. In a missed miscarriage, an embryo formed but stopped growing, and a heartbeat that should be seen is absent. Either way, the practical care is similar.

Why Does It Happen?

The most common reason is a chromosomal problem in the embryo. This means that when the egg and sperm came together, the genetic material did not combine in a way that allows normal development. The body recognises this, and the pregnancy does not continue. This can happen in any pregnancy, whether natural or after IVF, and it becomes more common with age, because eggs are more likely to carry chromosomal changes as a woman gets older.

Other factors your doctor may look into, especially if this happens more than once, include the shape of the womb, hormone and thyroid conditions, and clotting problems such as antiphospholipid syndrome. You can also read about thyroid and fertility.

What does not cause it: exercise, a stressful day, lifting something, travelling, a moment of anger, intimacy, or a food you ate. Please let go of the "what if I had" questions. They have no answer, because nothing you did could have changed it.

How Is It Found?

Often it is found at a routine early scan, when the doctor sees an empty sac or cannot find a heartbeat where one is expected. Sometimes there are signs, such as light bleeding or the loss of early pregnancy symptoms, but many women have none at all.

Because the timing of early pregnancy can be tricky, a good doctor will sometimes repeat the scan and blood tests before confirming the diagnosis, to be sure. If your doctor suggests waiting for a repeat scan, it is usually to avoid a mistake, not to be unkind. Ask what each result means and what you should do if bleeding or pain starts in the meantime.

What Are the Options for Management?

Once the diagnosis is confirmed, your doctor will discuss what is safest for you. The usual choices are:

• Waiting for the body to pass the pregnancy naturally — suitable for some women, with follow-up to make sure everything has cleared.
• Medicine — tablets that help the womb empty, taken under medical guidance, with a follow-up check afterwards.
• A minor surgical procedure — a short procedure to clear the womb, which may be advised if there is heavy bleeding, infection or other concerns.

None of these is right for everyone. Which is best depends on your health, your scan, and what you feel comfortable with. If you feel rushed, you can ask for time to think, unless your doctor tells you that you need urgent care.

Please contact your doctor straight away, or go to an emergency department, if you have very heavy bleeding, severe pain, fever, or feel faint or unwell.

Recovery and What to Expect

Physically, you may have bleeding and cramps for some time, and your body needs rest. Your doctor will tell you what to expect, what is normal and what needs a call. A follow-up visit is usually advised to confirm that the womb has cleared and to answer your questions.

Hormones can take a little while to settle, which can affect your mood, sleep and energy. If you have had IVF, your care team can also advise you on next steps for any remaining embryos, and on timing for a frozen cycle, which you can read about in frozen embryo transfer.

The Emotional Side

A loss like this can feel strangely unreal. There may have been no symptoms, no moment of change, and yet a hope that had already begun to grow has gone. This is real grief, and it deserves to be taken seriously, even when others say things like "it was early" or "at least you can try again."

Partners can be affected too, in different ways and at different speeds. Some people feel sad, angry or numb. Some feel guilty or want to avoid talking about it. All of this is normal. There is no timetable for healing. The feelings after a miscarriage following a positive IVF test may be familiar, and many people find it helps to talk, to a partner, a trusted friend or a counsellor. If you are finding it hard to cope, or the sadness is not easing, please speak to your doctor. You may also find IVF and your marriage helpful for staying connected as a couple.

Trying Again

Many women who have a blighted ovum or a single missed miscarriage go on to have a healthy pregnancy. A single early loss usually does not point to a lasting problem, and often the next pregnancy is not affected.

When to try again is a personal choice, and a medical one too. Your doctor can advise you on when your body is ready, and you may also want to give yourself emotional time. If you had IVF, your team will help plan the next step. If losses happen more than once, it makes sense to ask about further testing, and about options such as genetic testing of embryos where it may help. Whatever you decide, there is no deadline set by anyone but you.

Common Myths About Blighted Ovum and Missed Miscarriage

• Myth: "I must have done something to cause this." — These losses are most often due to chromosomal changes in the embryo, which no one can control.
• Myth: "If I felt fine, the pregnancy must be fine." — Many early losses have no symptoms at all, which is why they are called silent or missed.
• Myth: "A positive pregnancy test means the baby is growing." — Pregnancy hormones can continue for a while even when the embryo has stopped developing, so a scan is needed to confirm.
• Myth: "It will happen again every time." — Most women who have one early loss go on to have a healthy pregnancy.
• Myth: "I should just move on quickly and not talk about it." — Grief after pregnancy loss is real, and talking about it, with support, can help healing.

When to See a Doctor

Please see your doctor if a scan shows an empty sac or no heartbeat, so you can talk through your options and get the right follow-up. Seek urgent care if you have heavy bleeding, severe pain, fever or feel faint. If you have had more than one pregnancy loss, ask about investigations to look for treatable causes. And if you are struggling emotionally, tell your doctor, since support is part of your care. For more context, see our guides on ectopic pregnancy and secondary infertility.

Frequently Asked Questions

What is a blighted ovum? It is a pregnancy where a sac forms in the womb but the embryo does not develop, or stops very early. It is also called an anembryonic pregnancy.

What is a missed miscarriage? It is when an embryo has stopped growing but the body has not yet passed the pregnancy, so there may be no symptoms until a scan shows it.

Why do I still feel pregnant or have a positive test? Pregnancy hormones can remain for a time after development stops, which is why symptoms and tests may continue until the pregnancy is passed or treated.

Is it my fault? No. Most are caused by chromosomal problems in the embryo, and nothing you did, ate or felt caused it.

How is it treated? Depending on your situation, options include waiting, medicine or a minor surgical procedure. Your doctor will explain which is safest for you.

Can it happen after IVF? Yes. Pregnancy loss can happen in IVF as in natural pregnancies, and it is not a sign that the treatment was done wrongly.

Will it happen again? Most women who have one early loss go on to have a healthy pregnancy. If it happens more than once, your doctor may suggest tests to look for causes.

How long should we wait before trying again? This depends on your recovery, your treatment and how you feel. Your doctor can guide you, and you can also take emotional time before you feel ready.
