Signs and symptoms of an early miscarriage (or chemical pregnancy) would generally be spotting or vaginal bleeding similar to a menstrual period, and possibly some abdominal cramping. The bleeding might have more clots than a menstrual period; the clots would look like tiny lumps in the vaginal discharge.
Symptoms of a miscarriage include: 1  Vaginal bleeding that may be light or heavy, constant or irregular. 2  Although bleeding is often the first sign of a miscarriage, first-trimester bleeding may also occur with a normal pregnancy. 3  But bleeding with pain is a sign that miscarriage is more likely.
