Always seek emergency care if you are experiencing the symptoms of a miscarriage. Symptoms of a miscarriage include:
enough vaginal bleeding to soak more than one feminine pad in an hour
unbearably severe pain in the abdomen or pelvic region
clots or clumps of tissue (typically gray or pink in color) passed from the vagina
If you pass clots or clumps from the vagina, try to save the material in a jar or plastic bag to give to the doctor for analysis. He or she may then determine the cause of the problem.
