Abdominal pain after vaginal insertion of oxytocics may be a symptom of the opening of the uterus and the onset of labor. Most of the oxytocics inserted vaginally before delivery are misoprostol, which is a prostaglandin-type preparation that can soften the cervix and start contractions, and most of the reactions appear soon after the insertion of oxytocics, including pain in the abdomen, contractions, softening of the cervical canal, etc., with gradual shortening of the cervix and opening of the uterine orifice. The use of oxytocics in the prenatal period is associated with contractions, regular contractions in the abdomen, redness in the vagina, and a feeling of falling, etc. The use of oxytocics under the supervision of a doctor is necessary, as well as a vaginal check of the opening of the uterus. You should talk to your doctor about your symptoms and prepare for the delivery of your baby.
