Induced abortion is needed in the third month of pregnancy because the fetus is already formed and is too large for an abortion to be performed. It is necessary to induce the fetus to be expelled before the induction of labor can be completed. Most of the methods of induction of labor are drug-induced abortion and water-bladder-induced abortion. Most of the drug-induced abortions are performed by injecting Levanox into the uterine cavity, and then the uterus contracts and the opening of the uterus opens wide. There is also a method to induce labor by putting a capsule into the uterine cavity, and then remove it after 24 hours, the pregnancy may be expelled from the body, and it is also necessary to clean the uterus again.
