For women who terminate pregnancy by medication abortion, they need to take mifepristone tablets first and then misoprostol on the third day. The discharge of blood clots after taking mifepristone tablets is actually the effect of mifepristone, which leads to unstable embryo growth and a pre-eclampsia or even spontaneous miscarriage. If there is only a small amount of blood clot, it is considered to be pre-eclampsia, when the embryo has not yet been expelled. However, if there is already a large amount of blood clots and even white chorionic tissue is seen, it means that the embryo has been eliminated from the uterine cavity and this is a spontaneous abortion due to mifepristone. If the ultrasound is checked and there is no more visible other tissue in the uterine cavity, misoprostol can be dispensed with and this is already considered a successful medical abortion.
