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.
Early miscarriage refers to loss of a pregnancy in the first trimester. The majority of early miscarriages occur before the pregnancy is 10 weeks gestation. Some miscarriages happen very early, even before a woman is sure she is pregnant. Still, miscarriage can be a hard and sad experience, no matter when it occurs.
