What Is an Incomplete Abortion?

An incomplete abortion means that part of the pregnancy tissue has passed, but some remains inside the uterus. Doctors may also call this retained products of conception. It can happen after a miscarriage or after a medication or surgical abortion.

The remaining tissue can stop the uterus from closing down properly. This can lead to ongoing bleeding and infection, which is why an incomplete abortion should always be checked by a doctor.

Signs of an Incomplete Abortion

Bleeding that won’t settle

Heavy bleeding, or bleeding that continues for weeks instead of slowly easing.

Ongoing cramps

Strong cramping or lower abdominal pain that does not improve.

Signs of infection

Fever, chills or foul-smelling vaginal discharge.

Pregnancy symptoms continue

Nausea or breast tenderness that does not fade, or a pregnancy test that stays strongly positive 4–5 weeks later.

Some bleeding and cramping are normal after an abortion. To understand the usual pattern, read what to expect after taking abortion pill. The difference is that normal symptoms gradually get better, while an incomplete abortion does not.

Why an Incomplete Abortion Happens

  • Later pregnancy: the risk is higher as pregnancy advances, which is why care after about 12 weeks takes place in hospital.
  • No medical follow-up: without a check-up, retained tissue may go unnoticed.
  • Fake or wrong medicines: pills bought online may contain too little medicine, the wrong medicine or none at all. Learn the warning signs in our guide to fake abortion pills.
  • Natural miscarriage: a miscarriage can also be incomplete, even without any medicine.

How Doctors Diagnose It

  1. Questions and examination: the doctor asks about your bleeding, pain and any medicines taken, and checks your temperature, pulse and blood pressure.
  2. Ultrasound: the main test. It shows whether tissue remains in the uterus.
  3. Blood tests: to check for blood loss, infection and pregnancy hormone levels.

Be honest with the doctor about any pills you took, including where they came from. This helps them choose the safest treatment.

Treatment Options for Incomplete Abortion

The right treatment depends on your symptoms, how much tissue remains and how far along the pregnancy was. The World Health Organization describes three main approaches:

OptionWhat it involvesWhen it may be suitable
Watchful waitingLetting the tissue pass naturally, with follow-up checksMild symptoms, small amount of tissue, no signs of infection
MedicineMedicine given by a doctor to help the uterus emptyStable patients who prefer to avoid a procedure
Vacuum aspirationA short procedure that gently removes the remaining tissueHeavy bleeding, infection, larger amounts of tissue, or when other options fail

If there are signs of infection, antibiotics are also given. All three options should only be used under medical care.

“Cleaning Pills” After Abortion: What People Mean

Many people search for “cleaning pills after abortion”, hoping to finish an incomplete abortion at home. There is no safe cleaning pill to take on your own.

  • Doctors do sometimes use medicine to help the uterus empty, but only after an ultrasound and examination.
  • Taking extra pills without a scan can cause heavy bleeding and can hide a serious problem, such as infection or an ectopic pregnancy.
  • Pills sold as “cleaning” or “uterus wash” tablets online are unproven and often fake.

If you think tissue has stayed behind, the safe step is to see a doctor, not to take more pills.

When to Get Emergency Care

Go to the emergency department now if you have:

  • Bleeding that soaks two or more large pads an hour for two hours in a row
  • Large clots with dizziness, fainting or a fast heartbeat
  • Fever above 38°C, chills, or foul-smelling discharge
  • Severe abdominal pain that painkillers don’t relieve
Emergency: 997MOH helpline: 937

Hospitals in Saudi Arabia treat miscarriage and pregnancy complications. Doctors focus on treating the symptoms in front of them. For a full list of warning signs, see our page on abortion pills side effects.

Recovery After Treatment

  • Bleeding usually becomes lighter over the following days and stops within about two weeks.
  • Your period usually returns within 4–8 weeks.
  • Follow-up: attend any check-up your doctor arranges, and return sooner if bleeding, pain or fever comes back.
  • Emotional support: it is normal to feel tired, sad or anxious. Talk to your doctor if these feelings don’t ease.
