Placenta Grade 3 at 36 weeks does not mean that labor is imminent, but suggests that the placenta may be aging prematurely. Generally, after the third level of placenta, the function of the placenta will gradually decline, which may affect the blood supply and oxygenation of the fetus to a certain extent, but when the delivery still depends on the week of pregnancy, the cervical ripening and the contractions. In late pregnancy, when the cervix is ripe and there are regular contractions or vaginal discharge, it is possible to enter the period of labor, and it does not mean that the placenta level 3 will be in labor, and labor is not directly related to the maturity of the placenta. Placenta class III at 36 weeks of pregnancy, should closely observe the fetal movement and fetal heartbeat changes, regular prenatal checkups in the hospital, generally 36 weeks of pregnancy after the weekly checkups, regular monitoring of fetal growth, if there is intrauterine fetal hypoxia should be terminated in a timely manner.
