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 miscarriages occur in the first trimester and account for 80 percent of all miscarriages. Of these, a large number occur in the first weeks of pregnancy, often before a woman even knows sheâs pregnant. Late miscarriages and much less common, occurring in 1 in 1,000 pregnancies, and happen between the end of the first trimester and week 20.
