what the fuck are you talking about? abortions are a type of miscarriage and miscarriages are a type of abortion. the only difference is how they occur: miscarriages are spontaneous loss of the fetus & termination of pregnancy, while abortions are preceded by some event that causes the spontaneous loss of the fetus & termination of pregnancy. you can literally remove that antecedent event by qualifying "abortion" with "involuntary."
