The fetus can grow 800-1000 grams in the last month of late pregnancy. The growth rate of the fetus in the last month of late pregnancy is still relatively rapid, every pregnant woman’s body and nutritional situation is different, so the growth of the fetus will also be different, generally the last month can grow 800-1000 grams, but this is not absolute. Some pregnant women may increase the weight of the fetus even more if they eat more, and if they eat less, they may not be able to grow to this weight. The last month of late pregnancy maybe some pregnant women deliver in less than 40 weeks and don’t end up growing to a month, gaining a little less weight. If the ultrasound finds a small fetus in late pregnancy, you can increase nutrition appropriately to promote fetal growth. If the ultrasound finds that the fetus is large, you need to control your diet appropriately to prevent the fetus from gaining too much weight during labor and delivery and having a difficult delivery.
