There is no way to have a normal abortion in the fourth month of pregnancy; instead, an induced abortion is required. This is because in the fourth month of pregnancy the fetus has already been shaped, there are bones forming, and you can clearly see the fetus’ limbs, torso, and head. There are several options for inducing labor in the fourth month of pregnancy: First, you can choose to use a water bladder to induce labor, which means that a water bladder will be inserted into the uterine cavity and cervix in order to soften and stimulate the cervix, and then you can choose to use misoprostol to promote uterine contractions, so as to achieve the purpose of inducing labor. Secondly, intrauterine injection of Levano can be chosen. Intrauterine injection of Levano can kill the embryo, and after killing the embryo, it can cause uterine contractions, thus achieving the purpose of inducing labor. Thirdly, you can choose to use the use of hysterotonin or misoprostol to induce labor. But before using these two drugs, usually first use mifepristone to kill the activity of the embryo, and then use one of these two drugs to promote uterine contractions, so as to achieve the purpose of inducing labor.
