At 38 weeks of pregnancy, placental maturity grade 2 plus, which is usually in the normal range, indicates that the placenta has matured and is ready for subsequent delivery, so there is no need to worry excessively, and usually no need for special treatment. Placental maturity grading is mainly according to the shape of the placenta, the state of the placenta is divided into 1, 2, 3, as the placenta maturity grading increases, the calcification of the placental tissues will be more and more obvious, which indicates that the function of the placenta may deteriorate, which will adversely affect the absorption of oxygen and nutrients by the fetus. At this time, the maturity of the placenta is consistent with the gestational week, and the placenta has not matured prematurely or delayed, so it can be considered a normal situation.
