What are the symptoms of a miscarriage?

Signs of a Miscarriage:

"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 provider 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. "
