Fetal sac position
It is often determined by the implantation position of fertilized eggs. Its normal position should be in the base, front wall, back wall, upper part and middle part of the uterus, and its shape is round, oval and clear.
When the pregnant mother's fetal sac position is low, she should pay attention to rest and wait for the fetal sac to grow to a normal position. However, if the pregnant mother has abdominal pain and vaginal bleeding at the same time, there is the possibility of miscarriage.
