Placenta III is normal in late pregnancy. Placenta III has the ability to supply blood and oxygen to the fetus as well as the ability to transport nutrients to the fetus so that the fetus can grow normally in the uterine cavity. However, it is necessary to do fetal heart monitoring regularly to observe whether the fetus is hypoxic in the uterine cavity, to do ultrasound to measure the fetal umbilical cord blood flow resistance index, and to count the fetal movements at home to detect the safety of the fetus in the uterus. After 38 weeks of gestation, if the placenta reaches level 3 on ultrasound and there is no contraindication to vaginal delivery, pregnant women are advised to be more active to promote the fetal head into the pelvis and descent.
