Pregnancy 40 + 5 red pain is not so strong, mostly recommended for normal delivery, combined with the indication of cesarean section can choose cesarean section. Delivery methods include cesarean section and normal delivery. The choice between cesarean section and normal delivery depends on the condition of the fetus and the mother. As the cervix dilates, the nearby membranes separate from the uterine wall, and the capillaries rupture, causing redness. Redness is a reliable indicator of impending labor. If there are no contractions for a long time after the redness of 40+5, or if the contractions are mild, labor can be induced by promoting cervical ripening and then by contracting the uterus. Cesarean section is not usually an immediate option, except when combined with an indication for cesarean section. Pregnancy 40 + 5 red pain is not so strong does not necessarily have to be a cesarean section, but to actively promote cervical ripening after induction of labor, so as not to cause the expiration of pregnancy.
