It is impossible to expel the placenta in a medical abortion because clinically, a medical abortion can only be performed within seven weeks of pregnancy. At this time, the placenta has not yet formed, so even if the abortion is complete, there is no placental tissue among the excluded pregnancy products, so it is impossible to expel the placenta in a medical abortion. It is recommended that before having a medical abortion, a detailed examination must be done, mainly to grasp the indications for medical abortion. The first is that the abortion must be performed between 5 and 7 weeks of pregnancy and must be intrauterine. Secondly, before having a medical abortion, you should also have a routine white belt test, routine blood test, clotting time test and electrocardiogram test to understand the basic health condition of your body. If you have inflammation, you should not have a medical abortion because the inflammation may cause retrograde infection and pelvic inflammatory disease after the medical abortion, resulting in serious consequences.
