What are the reference values for the size of a baby at 34 weeks of pregnancy?

Patient's question:

Detailed medical condition and consultation purpose: Baby's size at 34 weeks of pregnancy

Doctor's answer:

Hello, the fetal biparietal diameter is 8.4 cm, equivalent to 34 weeks of pregnancy, the head circumference is 31.0 cm, equivalent to 34 weeks of pregnancy, the abdominal circumference is 30.5 cm, equivalent to 34 weeks of pregnancy, and the femur length is 6.5 cm, equivalent to 33 weeks of pregnancy. According to the color Doppler ultrasound results, the fetal development is normal and consistent with the actual gestational age. The fetal heart rate and amniotic fluid index are within the normal range. Occasional pain on the left side of the abdomen is not a major issue, possibly related to pressure from the enlarged uterus. It is important to maintain a relaxed mood and attend prenatal check-ups on schedule.
