If you are pregnant for 4 and a half months and do not want the baby, you should go to the community or the family planning department to get a certificate of induction of labor and go to the hospital for induction of labor, and after the hospitalization, check the blood and urine routine and do coagulation tests. If there is no abnormality in any of these, Levanox 100mg will be injected into the amniotic cavity. 24 hours after the injection, contractions may occur, which are light at first and gradually increase. As the contractions intensify, the opening of the uterus will widen, and when the opening of the uterus widens by 5 cm, the fetus may be delivered, and then the uterus will be cleared, i.e., clamped.
