Fetal weight varies among individuals and is affected by race, genetics, nutrition, placental function, etc. The average fetal weight at 29 weeks of pregnancy is about 1300 grams. The average fetal weight at 29 weeks of pregnancy is about 1300 grams. The fetus has some viability. The average fetal length at 29 weeks of pregnancy is about 38-43 cm, the average biparietal diameter is 7.50 plus or minus 0.65 cm, the average abdominal circumference is 23.71 plus or minus 1.50 cm, and the femur length is 5.61 plus or minus 0.44 cm. The muscles and lungs are continuing to mature and the fetal subcutaneous fat is tentatively forming, appearing rounder than before and no longer looking like a little old man; the fingernails are also well defined. The head is gradually enlarging and billions of neuronal cells are being generated in the brain. In the case of a boy, the testicles have descended from the abdomen; in the case of a girl, the fetus’ protruding labia minora can be seen. The fetus is moving more during this period, and it is also more obvious that the fetus can be seen moving from the abdomen. The fetal position is not very fixed at this time, sometimes head up, sometimes head down, changing frequently. A reasonable diet and appropriate activities will help the fetus grow and develop. Regular check of fetal position and close observation of fetal movement are the most crucial in this period. Do obstetric checkup once in two weeks, and make sure not to do the same as before, sometimes once a month. If you miss the checkup, you may miss the opportunity to detect fetal abnormalities and the time to intervene and increase the chances of difficult delivery.
