The bleeding might have more clots than a menstrual period; the clots would look like tiny lumps in the vaginal discharge.
Symptoms of miscarriage include: 1  Vaginal bleeding that may start as a brownish discharge. 2  Cramps or other pain in the pelvic area, lower back or abdomen. 3  A decrease in the usual signs of early pregnancy, such as nausea and breast tenderness.
