The position of the umbilical cord at the edge of the placenta usually does not change.
Under normal circumstances, the umbilical cord is usually in the middle of the placenta, which is a more nutritious position, but there are some fetuses whose umbilical cord will be at the edge of the placenta, in which case the umbilical cord will usually not change its position again.
In the case that the umbilical cord is not in the middle of the placenta, first of all, you need to observe whether the growth and development of the fetus is affected, and whether there is any vaginal bleeding, etc. If everything is normal for the fetus, and there is no discomfort, then there is no need to be overly nervous, and you can just go to the hospital for regular checkups.
If the fetal umbilical blood flow and fetal movement are abnormal during growth and development, then it is possible that the fetus is suffering from hypoxia and needs to go to the hospital immediately for treatment.
