Placental maturity grade II in 32 weeks of pregnancy is normal. Under ultrasound, according to the maturity of the placenta, the placenta is classified into grade 0, grade I, grade II and grade III. Placental grade II indicates that there is a bit of linear strong echogenicity in the parenchyma of the placenta, and a small portion of the blood vessels are fibrotic, which belongs to the mature placenta. However, the blood flow of the placenta is still good and can provide enough nutrients and oxygen for the fetus. After 32 weeks, pregnant women should pay attention to regular obstetric examination and fetal heart rate monitoring. As long as the score of fetal heart rate monitoring is high, pregnant women do not need to be nervous and can count the fetal movement at home. Pregnant women should also pay attention to dietary balance, increase the intake of high-quality protein and fresh vegetables.
