What’s the difference between abortion and miscarriage?
A miscarriage is the sudden loss of a pregnancy and death of the developing embryo or fetus before the 20th week. While the technical medical term for a miscarriage is “spontaneous abortion,” naturally occurring miscarriage should not be confused with abortion as used in common parlance to refer to the intentional killing of a developing embryo or fetus.
