Symptoms and Treatment of Incomplete Miscarriage

Updated July 14, 2014

A miscarriage is labeled "incomplete" if the bleeding has begun and the cervix is dilated, but tissue from the pregnancy still remains in the uterus.

Most of the time, a miscarriage that is "incomplete" at the time of diagnosis will run its course without further intervention, but sometimes the body has trouble passing the tissue from the pregnancy and the miscarriage remains incomplete until the woman seeks treatment. An incomplete miscarriage diagnosis is not the same as a missed miscarriage, a nonviable pregnancy in which the baby is no longer developing but the cervix remains closed and no bleeding has begun.

Symptoms of Incomplete Miscarriage

The main signs of incomplete miscarriage are bleeding and cramping. A woman with these symptoms should see a doctor to determine whether the bleeding and cramping are due to miscarriage or some other factor. If the doctor diagnoses a miscarriage, the woman may have a D & C or choose to wait for the miscarriage to complete naturally.

About 90% of the time, a miscarriage that is incomplete at the time of the initial miscarriage diagnosis will complete without intervention should the woman wish to avoid a D & C. Sometimes, however, tissue remains in the uterus without the body passing it naturally. If bleeding and cramping continue for longer than two weeks, the woman may have retained tissue in the uterus that can pose a risk of infection if not treated.

Occasionally, even a D & C may fail to remove all the tissue from the uterus and need to be repeated. So women who have continued bleeding and cramping for more than two weeks following a D & C should also follow up with their doctors to determine whether or not additional treatment is needed.

Treatment of Incomplete Miscarriage

For women who have retained tissue for more than two weeks after a miscarriage diagnosis, the usual treatment would be D & C. Some doctors may also offer medication such as misoprostol (Cytotec) to boost the odds that the body will pass the remaining tissue without surgery.
