Incomplete miscarriages make up approximately 20 percent of all miscarriages. These losses occur most often between the 6th and 13th weeks of pregnancy. In incomplete miscarriages, not all products of conception (the baby, the sac or the placenta) expel naturally from the mother. Medical attention is required for this condition.
Observe your bleeding. In the majority of incomplete miscarriages, heavy bleeding, often with clotting, occurs. The bleeding may even gradually become heavier. However, in some instances, the bleeding may slow.
Determine if you are experiencing cramping. As the uterus tries to expel its contents, these uterine contractions can be painful. Cramping often accompanies the bleeding in an incomplete miscarriage.
Note if you are having pain. With an incomplete miscarriage, abdominal or lower back pain is common. You may also experience a tenderness of your abdomen or in your pelvis.
Have a doctor check if your cervix appears open. A doctor can do this either via ultrasound or a pelvic examination. An open cervix signals miscarriage, including incomplete miscarriage.
Observe the contents of the uterus. Using an ultrasound, your doctor can determine if anything from the pregnancy remains in your uterus. In cases of incomplete miscarriages, a doctor may see remnants of the baby, the amniotic sac or the placenta in the uterus.
