The time of delivery depends on the condition of the fetus and the mother and the week of pregnancy. If the fetal organs are mature and the mother has no abnormal discomfort, delivery can take place at the expected date of delivery, which is around 40 weeks of gestation. Placental maturity is a gradual process, and the distribution of each level of maturity varies and overlaps with each other in each week of pregnancy. However, regardless of the first week of gestation, the delivery is usually the same as normal, i.e. full-term delivery. Pregnant women with grade II placenta are recommended to review ultrasound regularly to monitor placental maturity. Usually, you need to ensure sufficient sleep and a light diet. Once regular contractions, fetal descent sensation and redness signs of labor appear, immediately send to hospital obstetrics department for delivery.
