An incomplete miscarriage is a pregnancy loss that results in only part of the fetus or placenta being expelled. This type of miscarriage can occur at any time prior to the 20th week of pregnancy; however, an incomplete miscarriage most commonly occurs prior to the 13th week of pregnancy, according to the American Pregnancy Association. An incomplete miscarriage is a medical emergency. As such, any pregnant woman with signs of one must go to the hospital for confirmation of the miscarriage and appropriate treatment.
Vaginal Bleeding
Vaginal bleeding is common with any type of miscarriage; however, in the case of an incomplete miscarriage, the bleeding is heavy and persistent as long as fetal matter remains in the uterus. Passing blood clots and pinkish-gray matter from the vagina is also possible. Additionally, the woman's water may break, just like any woman in labor.
Cramping
As is the case with any miscarriage, abdominal cramping is usually present with an incomplete miscarriage. The cramping may come and go like contractions come and go in a woman in labor. Back pain and pelvic pain may also be present. In an incomplete miscarriage, the cramping and pain won't stop until all fetal matter is expelled.
Dilation
During an incomplete miscarriage, a woman's cervix will dilate and will stay dilated until the miscarriage is complete. The cervix will also efface, just as it does when a woman is in labor. A vaginal exam may be performed to confirm dilation.
Infection
Because some fetal matter remains in the uterus when an incomplete miscarriage happens, infection is possible. In some cases, signs of a uterine infection are the only indications that the miscarriage has occurred. Fever, foul vaginal discharge that is thick, and lower abdominal pain are all signs of a uterine infection. Additionally, a woman may experience chills and flu-like aches.
