When your water breaks at 37 weeks of pregnancy, you should absolutely rest in bed and not walk on the floor. If you walk on the floor, it will cause too much amniotic fluid to flow out, and there is a possibility that the umbilical cord will prolapse. If the umbilical cord prolapses, it can affect the health of the fetus at any time, because the umbilical cord is used to transport nutrients and oxygen. If the umbilical cord prolapses, it can lead to intrauterine asphyxia, intrauterine ischemia and hypoxia of the fetus, and in severe cases, fetal arrest. If the amniotic fluid breaks, the baby should be born within 48 hours. If contractions are not produced within 48 hours, antibiotics should be administered promptly to prevent uterine infection. After the water breaks, bacteria may enter the uterine cavity retrogradely and affect the growth and development of the fetus. During this period, you should also pay attention to the change of fetal heartbeat, if the fetal heartbeat is not normal, you should promptly terminate the pregnancy and do a cesarean section.
