34-week b-ultrasound data standard?

I am now 34 weeks pregnant, and I pay special attention to the growth and development of the baby. I would like to know what is the 34-week b-ultrasound data standard?

The B-ultrasound examination of the pregnant woman at 34 weeks shows that the biparietal diameter of the normal fetus is between 7.98 cm and 9.24 cm, and the average value is 8.61 cm; the femur length is between 6.19 cm and 7.05 cm cm, the average value is 6.62 cm; the normal range of head circumference is 29.3 cm to 33.1 cm, the average value is 31.2 cm; the average value of abdominal circumference is between 27.99 ± 2.55 cm; the weight of the fetus is about 2300 grams; The hip diameter is about 30 cm. Due to individual differences, the growth and development of each fetus will be different, as long as the value is within the normal range, so pregnant women do not need to worry too much.
