When there is an implantation failure, the embryo has not yet attached to the uterus nor has the gestational sac formed. Therefore, there is no abortion per se. The transferred embryo that has not been implanted stops its development and is eliminated with the woman's next menstruation.
Can there be miscarriage due to implantation failure?
