One week of umbilical cord entanglement, although potentially dangerous, is a low probability and one week of umbilical cord entanglement is a common manifestation of pregnancy, so there is no need to be overly nervous. Most of the umbilical cords are long enough and have a certain degree of stretch, so the probability of fetal hypoxia and ischemia caused by wrapping within a certain range is low. If the umbilical cord is too short because of the free section of the umbilical cord after the cervical cord is wrapped around the neck, or if the umbilical cord is twisted or knotted after the cervical cord is wrapped around the neck or if the umbilical cord is wrapped around the neck too tightly, this may cause fetal ischemia and hypoxia, and then there will be fetal distress and other dangers. It is worth noting that one week of umbilical cord around the neck does not mean you can’t have a normal delivery, as long as the fetal movement and heartbeat are normal, pregnant women can choose to have a natural delivery. Therefore, after one week of umbilical cord around the neck, pregnant women should check the fetal movement regularly, if the fetal movement is too frequent or too little, go to the hospital for examination.
