The abdominal pain will appear only after 24 hours at the earliest after the induction of labor, that is, the contractions will gradually appear after 24 hours, and the contractions will be from light to heavy, from long to short intervals, and the opening of the uterus will slowly open up under the contractions. If the gestational period is longer, it will take longer because the opening of the uterus has to be bigger so that the pregnancy products can be completely expelled from the body and the placenta can be expelled only after the fetus is expelled first. It is clinically recommended to closely observe the abdominal pain and to know the opening of the uterus, and after the induction of labor, it is recommended to take oral milk retrieval medication and give a review after 1 month.
