How big is a normal fetus at 32 weeks pregnant

Patient's question:

I have an itchy lower body, and my underwear is always yellow. What's going on? How big is the fetus at 32 weeks of pregnancy?

Doctor's answer:

At 32 weeks (8 months), it is approximately 8.0 cm, and so on. After 8 months of pregnancy, the average growth of the biparietal diameter is about 0.2 cm per week, which is normal.
Femur length: The femur length is the length of the fetus's thigh bone. Its normal value is approximately 2-3 cm less than the biparietal diameter corresponding to the gestational month. For example, if the biparietal diameter is 9.3 cm, the femur length should be 7.3 cm; if the biparietal diameter is 8.9 cm, the femur length should be 6.9 cm.
