Anembryonic Pregnancy (Blighted Ovum): A Calm Guide for Indian Women

• An anembryonic pregnancy (blighted ovum) is an early pregnancy where the sac forms but no embryo develops; it is the most common cause of first-trimester miscarriage.
• It is overwhelmingly caused by random chromosomal errors in the egg, sperm, or early embryo, not by anything you ate, did, or felt.
• Diagnosis is made on transvaginal ultrasound, often confirmed with a repeat scan 7 to 14 days later to be certain before any treatment.
• Three management options exist: waiting for natural passage, medicines (misoprostol with or without mifepristone), or a minor procedure (MVA/D&C). Surgery is not always required.
• After a single loss, about 80 to 85 percent of women go on to have a healthy pregnancy; you can usually try again after one or two normal cycles, once you feel ready.

In a normal early pregnancy, a fertilised egg implants in the uterus and develops into two parts: the embryo (the baby) and the structures that support it, including the pregnancy sac and the placenta. In an anembryonic pregnancy, the sac and supporting tissue form, but the embryo either never develops or stops growing very early and is reabsorbed.

The placental tissue keeps making the pregnancy hormone hCG for a while, which is why your home pregnancy test stays positive and early symptoms like nausea and breast tenderness can continue. The body simply hasn't yet recognised that the pregnancy is no longer growing.

The older name "blighted ovum" is being replaced by "anembryonic pregnancy" because it is more accurate and less blaming. Both terms describe exactly the same thing. It is not a sign that your uterus or body is broken, and for most women it is a one-time event.

Anembryonic pregnancy accounts for roughly 30 to 50 percent of all first-trimester miscarriages. Because early miscarriage affects about 15 to 20 percent of confirmed pregnancies, this type specifically affects roughly 5 to 10 percent of clinically recognised pregnancies. It is far more common than most people realise, which is one reason it can feel so isolating: many women around you have experienced it without ever talking about it.

• Light bleeding or brown spotting in early pregnancy
• Mild cramping, similar to early period cramps
• Pregnancy symptoms (nausea, breast tenderness, fatigue) fading earlier than expected
• hCG levels on a blood test that plateau or rise more slowly than normal

• Thyroid problems, which are very common in Indian women and affect early pregnancy when poorly controlled
• Uncontrolled diabetes or significant insulin resistance
• PCOS, which is linked to a modestly higher early-loss rate
• High prolactin or other hormone imbalances
• Uterine factors such as fibroids that distort the cavity, scar tissue, or a septum
• Vitamin D and B12 deficiencies, which are widespread in India and worth correcting before conceiving

Many women replay every detail of the past few weeks looking for what they did wrong. This is understandable, but it is almost never accurate. The chromosomal error that caused the loss was set in motion before you even knew you were pregnant.

In Indian families, an early loss is sometimes blamed on a woman's diet, her work, the evil eye or nazar, or some imagined moral failing. None of this is supported by evidence, and it adds cruel and unnecessary guilt at the worst possible time. You are allowed to gently correct these beliefs, set boundaries on what you discuss, and ask your doctor to explain clearly that the cause was random. If grief feels heavy or won't lift, structured support for grief after a pregnancy loss is appropriate and increasingly available in India.

• The pregnancy sac measures 25 mm or more across with no visible embryo
• The sac measures 18 mm or more with no visible yolk sac
• There is no heartbeat in an embryo measuring 7 mm or more
• A repeat scan 7 to 14 days later shows no further development

Most women recover physically without complications. Bleeding usually settles over one to three weeks, and your next period typically returns within four to eight weeks, sometimes heavier than usual. Avoid tampons, swimming, and sex for about two weeks to let the cervix close and lower infection risk. A pregnancy test can stay positive for one to four weeks as hCG falls.

If you are Rh-negative, you may be offered anti-D injection to protect future pregnancies; ask your doctor whether you need it. If you would like to prevent pregnancy while you recover emotionally, contraception can usually be started straight away.

Emotional recovery is often harder than the physical side, and there is no "correct" way or timeline to grieve. Sadness, anger, guilt, and anxiety about the future are all normal, and partners often grieve differently and more quietly. Lean on trusted people, and consider counselling if the weight doesn't ease. If a future pregnancy brings fear and worry, that is extremely common, and support for anxiety after a pregnancy loss can genuinely help.

• Soaking more than one full pad an hour for two or more hours, or passing very large clots
• Fever above 38 degrees Celsius or shaking chills
• Severe pain not relieved by the pain medicine you were given
• Foul-smelling vaginal discharge
• Feeling faint, dizzy, or breathless
• Bleeding or pain that keeps getting worse instead of settling

For most women, a single anembryonic pregnancy does not lower the chance of a healthy pregnancy next time. About 80 to 85 percent of women who have one early loss go on to have a successful pregnancy, and the risk of another early loss stays close to the normal background risk of 15 to 20 percent.

You do not need to wait many months. Current WHO and ACOG guidance does not support fixed waiting periods; most women can try to conceive again after one or two normal cycles, once they feel emotionally ready. The old advice to wait three to six months is not evidence-based. Starting folic acid and other preconception steps before you conceive helps optimise the things you can control.

A second or third consecutive loss is different and deserves a proper workup, usually called recurrent miscarriage evaluation. This can include parental chromosome testing, uterine imaging, thyroid and blood-clotting tests, and is guided by ESHRE, with ICOG and FOGSI providing Indian-context adaptations. Where a specific cause is found, treating it improves outcomes. Where no cause is found, which is common, the outlook with supportive care is still reassuringly good. In some cases, options such as IVF with genetic testing of embryos or genetic counselling are discussed, but these are only relevant for a minority.
