When there is umbilical cord entanglement, if there is an increase in fetal movement frequency, it is important to consistently monitor the fetal movements. If, during monitoring, the fetal movements become especially frequent, or if there is a sudden cessation of movement after frequent movements, this is a very dangerous sign and immediate medical examination at a hospital is necessary. Additionally, regular prenatal examinations at the hospital should be conducted, such as fetal heart monitoring or ultrasound checks. It's also important to adopt a left lateral sleeping position to improve placental blood supply, avoid vigorous exercise, and maintain a relaxed mindset.
