At 39 weeks of pregnancy, finding a single loop of umbilical cord around the neck during an ultrasound should not be a concern; this condition is quite common among pregnant women and does not have a significant impact on the fetus, nor does it affect natural childbirth. At this time, the following aspects should be noted:

First, attention should be paid to any abnormal fetal movements. If there is an increase or decrease in fetal movement, it is necessary to come to the hospital for an examination to rule out hypoxia.

Second, be aware of signs of labor, including bloody show and contractions. If these conditions occur, you should come to the hospital promptly to await birth.

Third, it is important to attend routine prenatal check-ups a week later. Do not overly focus on the cord around the neck, as it generally does not cause hypoxia or affect the method of childbirth.
