Introduction
Under normal circumstances, sudden umbilical cord entanglement around the neck at 39 weeks of pregnancy may be caused by factors such as frequent fetal movement, excessively long umbilical cord, polyhydramnios (excessive amniotic fluid), overly vigorous fetal activity, or abnormal intrauterine environment. In the late stages of pregnancy, frequent fetal movements may lead to the umbilical cord wrapping around the fetus's neck during movement. The space available for free fetal movement within the uterus is limited.

Generally, sudden umbilical cord entanglement around the neck at 39 weeks of pregnancy may be caused by factors such as frequent fetal movement, excessively long umbilical cord, polyhydramnios (excessive amniotic fluid), overly vigorous fetal activity, or abnormal intrauterine environment. The details are as follows:

1. Frequent fetal movement: In late pregnancy, frequent fetal movements may lead to the umbilical cord wrapping around the fetus's neck during movement. Since the space for free movement within the uterus is limited, umbilical cord entanglement around the neck is relatively common.

2. Excessively long umbilical cord: An abnormally long umbilical cord can contribute to cord entanglement. A longer cord allows greater freedom of movement for the fetus within the uterus, increasing the likelihood of the cord wrapping around the neck.

3. Polyhydramnios: Excessive amniotic fluid is a condition that may occur in late pregnancy. It increases the fetus’s range of motion within the amniotic fluid, thereby raising the risk of umbilical cord entanglement.

4. Overly vigorous fetal movement: Some fetuses exhibit particularly strong movements inside the uterus, which may result in the umbilical cord wrapping around the fetal body. While fetal movement is normal, excessively intense activity can lead to cord entanglement.

5. Uterine fibroids: Uterine fibroids may cause irregular uterine contractions, thereby increasing the risk of umbilical cord entanglement.

Pregnant women are advised to attend regular prenatal checkups to avoid delayed diagnosis and treatment, preventing adverse outcomes.

Is it safe to have sexual intercourse at 39 weeks of pregnancy, and will it have any impact?
Under normal circumstances, sexual intercourse is not recommended at 39 weeks of pregnancy, as it may cause adverse effects. At 39 weeks, pregnancy has reached the late stage, and the woman's uterus becomes more sensitive. During sexual activity, the uterus may be stimulated, leading to contractions. Additionally, prostaglandins in male semen may also induce uterine contractions. Strong contractions can result in preterm labor.

Is it safe to eat lychee at 39 weeks of pregnancy?
If a pregnant woman's blood glucose levels are within the normal range at 39 weeks of gestation and she has good gastrointestinal function without symptoms such as constipation or internal heat, she may consume a small amount of lychee. Lychee is rich in glucose, vitamins, and other nutrients. Consuming 3–5 lychees per serving can quickly replenish energy, alleviate fatigue near the time of delivery, and the vitamin C content can help enhance immunity, thus helping to build up strength for labor.

Is feeling sleepy at 39 weeks of pregnancy a sign that labor is near?
In general, "labor" refers to childbirth. Drowsiness at 39 weeks of pregnancy may be a sign of fatigue during pregnancy, but it does not necessarily indicate that labor is imminent. At 39 weeks, pregnancy has entered the late stage, and drowsiness at this point could result from various factors, including but not limited to hormonal changes, increased fetal pressure, reduced sleep quality, greater physical strain, nutritional deficiencies, or anemia.

Treatment may include general management and medication under a doctor's guidance. To ensure a healthy pregnancy, pregnant women should maintain a balanced diet, avoid strenuous exercise and abdominal trauma, and monitor fetal movements regularly.
