Dear Pooja, Placental gradation suggests the maturity of the placenta. At 26 weeks of gestation, the placenta has not matured fully and hence grade 2 maturity is within normal expectations. As the pregnancy advances, the placental maturation will progress to complete maturation by term. At 27 weeks of gestation, ultrasonographically assessed foetal age of 24-26 weeks is not abnormal nor does it suggest growth retardation. Variation by a week or so by ultrasonography is permissible. I feel, you should take these investigations as within normal limits and monitor them in future. Continue to consume high protein, moderate carbohydrates and low fat diet with iron, folic acid and calcium in medicinal form regularly. I hope this helps you. Dr. Nishikant
