Miscarriage Summary
A miscarriage is any pregnancy that ends spontaneously before the fetus can survive. Miscarriage usually occurs before the 13th week of pregnancy. The cause of a miscarriage cannot always be determined. The most common causes of a miscarriage in the first trimester are collagen vascular disease (lupus), hormonal problems, diabetes, chromosomal abnormalities, and congenital abnormalities of the uterus.

Miscarriage Symptoms and Signs

If you are having a spontaneous miscarriage, you will probably have vaginal bleeding, abdominal pain, and cramping.

  • Bleeding may be only slight spotting, or it can be quite severe. Your health care practitioner will ask about how much you have bled-usually the number of pads you've soaked through. You will also be asked about blood clots or whether you saw any tissue.
  • Pain and cramping occur in the lower abdomen. They may occur on only one side, both sides, or in the middle. The pain can also go into your lower back, buttocks, and genitals.
  • You may no longer have signs of pregnancy such as nausea or breast swelling/tenderness if you have experienced a miscarriage.
