There are several methods of inducing labor: 5-7 weeks can be considered as a medicated abortion, 7-10 weeks can be considered as an abortion, 10-15 weeks can be considered as a medicated abortion, and after 15 weeks and into the late stages of pregnancy can be considered as an intra-amniotic levano induced abortion. Intra-amniotic levano induction of labor involves injecting a levano injection into the amniotic cavity, which can cause the baby to die and contractions to start, so it works 24 hours after the injection and up to 72 hours after the injection. If there is no sign of labor starting after 72 hours, consider inducing labor by another method, or another intra-amniotic levano injection, which is the most common method of inducing labor. If none of these methods are effective, you can consider inducing labor with a water bladder, which is mainly suitable for pregnant women who have a relatively mature cervix at a relatively large gestational age.
