If you usually have regular periods, it is appropriate to induce labor at 14 weeks of pregnancy. However, because of the large gestation month, the placenta and amniotic fluid have been formed, you need to be hospitalized before induction of labor, and you need a certificate of induction of labor issued by the family planning department before you can be hospitalized for induction of labor. Before the induction of labor, relevant auxiliary tests should be completed, including coagulation analysis, blood cell analysis, kidney function, liver function, electrocardiogram, obstetrical ultrasound, virus eight, etc. If the results of these tests are not abnormal and contraindications to induction of labor are excluded, labor can be induced. The common method to induce labor at 14 weeks of pregnancy is oral mifepristone combined with intra-abdominal injection of epsilon-acridine into the amniotic cavity. Usually the embryo is expelled 24-48 hours after the injection of ezacrine. During the process of induction of labor, it is important to closely observe the amount of vaginal bleeding of the patient.
