Incomplete abortion means the pregnancy has ended but some of the tissue is still inside the uterus. On a scan report you may see it written as retained products of conception, or RPOC. It is the same thing.
One point of language first, because it frightens people unnecessarily. In medicine, the word "abortion" means any pregnancy that ends before viability — including a natural miscarriage. If your report says "incomplete abortion" after a miscarriage, nobody is suggesting you did anything. It is simply the medical term.
This page explains what has actually happened, why it has to be dealt with rather than waited out, and why a surgical evacuation is the treatment that settles it.
These cannot wait for an appointment
- Soaking two or more pads an hour, or passing large clots.
- Fever, chills or shivering — with or without bleeding.
- Foul-smelling vaginal discharge.
- Severe or worsening lower abdominal pain, or pain on moving.
- Feeling faint, dizzy, breathless, or a racing heartbeat.
- Shoulder-tip pain, or one-sided pain with a positive pregnancy test — this can mean an ectopic pregnancy, which abortion pills do not treat.
Heavy bleeding and infection are the two things that turn a manageable problem into a dangerous one, and both move faster than most women expect. If you are unsure, be seen. Nobody will mind.
What has actually happened
When a pregnancy ends, the uterus has to do two things: expel the pregnancy tissue completely, and then clamp down to close the blood vessels that were feeding it.
Those two steps depend on each other. The uterus cannot contract down properly while something is still inside it. So when tissue is left behind, the uterus stays partly open and partly relaxed, the vessels at the placental bed stay open, and the bleeding continues. It is the same mechanism that causes heavy bleeding after delivery when a piece of placenta is retained.
That is the whole problem in one sentence, and everything else on this page follows from it.
How tissue comes to be left behind
- After a miscarriage. The commonest situation. The pregnancy passes, but incompletely.
- After medicines taken to end a pregnancy — particularly when taken without a scan first, without knowing the correct gestation, and without anyone checking afterwards that the uterus is empty. Supervised MTP care exists precisely to prevent this.
- After a delivery, when a fragment of placenta or membrane is retained. This shows up as heavy bleeding days or weeks later, called secondary postpartum haemorrhage.
- After a procedure that did not empty the uterus completely the first time.
Three in four, outside a facility
India recorded an estimated 15.6 million abortions in 2015, a rate of 47 per 1,000 women aged 15 to 49. Close to three in four were achieved with medicines obtained from chemists and informal vendors rather than from a health facility. Fewer than one in four happened in a facility at all.
Among women who then reach a hospital with a complication, 33% to 65% have an incomplete abortion from those medicines. Infection or inflammation affects 4% to 16% — on the order of hundreds of thousands of women a year. Sepsis runs at 3% to 7%, injuries such as perforation at 2% to 9%, and shock at 1% to 4%. These are not rare events at the population level. They are an everyday gynaecological emergency in this country.
Why it cannot simply be left
This is the section to read if you are being told to "wait and watch" while you are still bleeding.
- Bleeding that does not stop. As long as tissue is inside, the uterus cannot close the vessels. Blood loss accumulates quietly over days, and anaemia in an Indian woman who was often already anaemic before the pregnancy is not a small matter.
- Sudden heavy haemorrhage. Retained tissue can separate abruptly and open the vessels beneath it. This is how a woman who was "managing" for a week ends up needing a transfusion in a single afternoon.
- Infection, then sepsis. Retained tissue is dead tissue sitting in a cavity that is open to the vagina. It is an ideal culture medium. Septic abortion is one of the recognised contributors to maternal death in India, and it can progress from feeling unwell to being critically ill within a day.
- A missed ectopic pregnancy. If pills were taken without a scan, nobody confirmed the pregnancy was inside the uterus. Abortion medicines do nothing to an ectopic pregnancy, and continued bleeding is then falsely reassuring while the real problem grows.
- Damage from repeated attempts. Delay tends to end with more instrumentation, not less — a difficult procedure on an infected uterus rather than a straightforward one on a clean cavity.
- Delayed return to normal. Periods do not settle, the next pregnancy is postponed, and the uncertainty itself becomes exhausting.
Set against that, the argument for waiting is convenience. That is not a fair trade.
How it is diagnosed
Three things together: your history, an examination, and a scan.
The history matters more than people expect — how many weeks pregnant you were, what you took and when, how much bleeding there has been, whether tissue was passed, and whether a scan was ever done before the pregnancy ended. On examination, an open cervix, a uterus larger or more tender than it should be, and offensive discharge all point the same way.
On ultrasound, what is being looked for is not a single measurement. The picture that means retained products is a lining above about 10 mm that is heterogeneous — mixed in texture — with blood flow running through it on colour Doppler. The flow is the important part: a blood clot has no blood supply of its own, while retained tissue does. A low-resistance vascular pattern is the most specific finding there is.
Thickness on its own is a much weaker test — roughly 80% sensitive and 65% specific — which is exactly why a report saying only "endometrial thickness 14 mm" is not a diagnosis, and why the scan needs to be interpreted alongside everything else rather than read as a verdict.
Enhanced myometrial vascularity
Occasionally a scan after a pregnancy loss shows a tangle of turbulent, high-velocity vessels in the muscle of the uterus itself — enhanced myometrial vascularity, sometimes called a uterine arteriovenous malformation. It can look and behave like retained products, with bleeding and an abnormal scan.
It must be recognised, because curetting it can cause torrential bleeding. This is why "just get a D&C done somewhere" is not the same as being properly assessed first, and why the scan should be looked at by someone who is asking this specific question. It is uncommon — but it is the reason the assessment comes before the procedure, not after it.
Treatment: why surgical evacuation is the answer
There are three approaches in the textbooks — wait, medicines, or a procedure. In practice, for a woman with retained products who is still bleeding, surgical evacuation is the treatment that reliably ends the problem, and it is what I recommend in most cases. Here is the reasoning, with the evidence.
It works better, and that is measurable
A meta-analysis of 27 trials and 3,177 women compared the three approaches for first-trimester miscarriage. Surgical management achieved complete emptying of the uterus significantly more often than medicines — a difference of 32.8 percentage points in favour of surgery. Put another way, for every three women treated surgically rather than medically, one more has a completely empty uterus.
And the point that settles the argument: across all of those comparisons there were no differences in major complications — not in bleeding, not in transfusion, not in infection. Surgery was more effective without being more dangerous.
It finishes the problem in one visit
Medicines ask you to bleed at home for days, then return for a scan to find out whether they worked, and to accept a real chance of needing the procedure anyway at the end of it. Surgical evacuation empties the uterus in a matter of minutes, the bleeding settles quickly afterwards, and you know where you stand the same day.
That certainty is worth more in India than the trial data alone suggests. Medical management is only as safe as the follow-up attached to it. A woman who lives far away, who cannot easily return, who has no one to bring her back if she starts bleeding heavily at 2 a.m., or who will simply not come back once the pain settles, is not getting the treatment the trials studied. An approach that depends on a second visit that may not happen is not the safer option, whatever the leaflet says.
It gives an answer as well as a treatment
The tissue removed can be sent for histology. That confirms the pregnancy was intrauterine, and in rare cases identifies a molar pregnancy that needs specific follow-up — something no course of tablets will ever tell you.
Sometimes there is no choice at all
Surgical evacuation is not a preference but a necessity when there is heavy or continuing haemorrhage, signs of infection or sepsis, haemodynamic instability — a fast pulse, a falling blood pressure, feeling faint — or when medicines have already been tried and failed. In those situations, waiting is the risk.
Where medicines do fit
They are not useless, and it would be dishonest to say so. Misoprostol is a reasonable option for a woman who is clinically stable, not bleeding heavily, has no sign of infection, has a small volume of retained tissue, and can genuinely return for the follow-up scan that confirms the uterus is empty. Some women strongly prefer to avoid a procedure, and that preference deserves respect.
What is not reasonable is drifting into medical management by default — a prescription, a vague instruction to come back if it gets worse, and no scan booked. That is how a treatable problem becomes an emergency. If medicines are used, the follow-up scan is part of the treatment, not an optional extra.
What the procedure actually involves
The modern operation is a suction evacuation — gentle vacuum aspiration, not the vigorous scraping the phrase "D&C" brings to mind. The cervix is gently opened if needed and a soft cannula attached to suction empties the cavity. It takes a few minutes.
This distinction is not cosmetic. Suction is the technique that international guidance recommends in place of sharp curettage, and in a retrospective study of more than 80,000 women, vacuum aspiration carried less than half the rate of major and minor complications compared with sharp curettage — along with less blood loss, less pain and a shorter procedure.
Practically: you will be asked to fast beforehand, blood tests and a blood group check are done, you are given anaesthesia so you feel nothing, and you go home the same day in most cases. Cramping and bleeding like a period follow for a few days and then settle. Antibiotics are given where infection is present or likely.
What about adhesions? An honest answer
This is the objection worth taking seriously, and we have written about it separately because it matters: intrauterine adhesions — Asherman's syndrome — are reported in roughly 16 to 19 in 100 women after surgical evacuation for miscarriage, and most of those are mild.
That risk is real and it should be part of the conversation. Three things put it in proportion:
- The risk rises with repeated procedures, not with having one done properly. Choosing to wait often means two attempts instead of one.
- The technique matters. A single gentle suction evacuation is not the same operation as repeated sharp curettage, which is what most of the historical adhesion data describes.
- The alternative carries its own costs. Weeks of bleeding, anaemia, infection and an inflamed cavity are not neutral for the endometrium either.
The answer is not to avoid the operation. It is to have it done once, gently, completely, and by someone who is not in a hurry.
Recovery, and what comes next
- Bleeding settles over a few days to about two weeks, lighter than a period by the end. Bleeding that increases, or a fever, means come back.
- Your period usually returns in four to six weeks.
- Anti-D. If your blood group is Rh negative, you should receive anti-D immunoglobulin. Ask about it explicitly — it is missed more often than it should be, and it protects future pregnancies.
- Contraception is needed straight away if you do not want to conceive: ovulation can return within about two weeks, before any period. A device or an implant can be fitted at the right point, and our page on long-acting contraception covers the options.
- Nothing in the vagina — no tampons, no intercourse — until bleeding has stopped and you have been advised it is safe, usually about two weeks.
- Trying again. Once bleeding has settled and you feel ready. There is no medical requirement to wait several cycles after a single loss; our page on planning a pregnancy after a miscarriage covers the timing and what is worth checking first.
If this was your second or third loss, that changes the conversation from treatment to investigation — see recurrent miscarriage.
What to bring, and what to ask
- Any scan reports, including anything done before the pregnancy ended.
- The names of anything you took, the strength, and the dates — bring the strip or the box if you still have it. Nobody is going to judge you for this, and it genuinely changes the assessment.
- Your blood group, if you know it.
- A rough account of the bleeding: how many pads, over how many days.
The questions worth asking: is the uterus empty or not; is there any sign of infection; do I need anti-D; and what exactly is the plan if the bleeding does not stop?
What happens at the clinic
Consultation and assessment, examination, blood tests including blood group and haemoglobin, going through your reports, antibiotics and other medication including intravenous treatment where it is needed, anti-D, contraception afterwards and the follow-up — all of this happens at the clinic. Scans are arranged by referral, since we do not run an ultrasound machine here.
Surgical evacuation is done at hospital, with admission for the day and an anaesthetic. It is not a clinic-room procedure anywhere, and it should not be presented as one.
If you are bleeding heavily, feverish or unwell right now, go to a hospital emergency department rather than waiting for a clinic appointment. If you are stable and simply do not know what your report means, bring it in and we will go through it.
