Is it normal for the biparietal diameter to be 5.5 cm at 24 weeks of pregnancy?

Patient's question:

No

Doctor's answer:

Hello, generally at 24 weeks of pregnancy, the normal average biparietal diameter of the fetus is 61 mm, the femur length is 43 mm, the head circumference is 21.6 cm, and the abdominal circumference is 18.8 cm. The maximum depth of the amniotic fluid dark area is greater than 2 cm and less than 7 cm.
According to your test results, the fetus is slightly smaller in development, but it is within the normal range. The amniotic fluid is normal. You should increase your nutrition, ensure adequate sleep, and regularly monitor the situation.
