Lower abdominal pain after induction of labor is generally normal, as it refers to the process of expulsion of the fetus and its appendages after 12 weeks of gestation. When the fetus and appendages are expelled, the uterus will contract, and this contraction is a protective mechanism to reduce the possibility of uterine bleeding, and will be accompanied by pain in the lower abdomen, which will be paroxysmal. If there is significant paroxysmal pain in the lower abdomen, it is also indicative of good uterine contractions and can be combined with observation of vaginal bleeding. If the pain in the lower abdomen is accompanied by a small amount of vaginal bleeding, this is a normal condition. However, if the pain in the lower abdomen occurs several days after ovulation, it is important to consider the possibility of secondary pelvic infection in conjunction with the presence of generalized fever in the woman and give follow-up treatment.
