During pregnancy, the growth of the baby can be observed through examinations such as ultrasound and color ultrasound. It can also measure various data of the fetus. Doctors will use data such as head circumference, body length, and femur length to assess a child's condition. So, at 39 weeks, is the femur length 6.73 and the legs short?
At 39 weeks of pregnancy, the standard value for fetal femur length is 7.34 centimeters. If the femur length is 6.73, it is also considered normal and not a short leg. After a woman becomes pregnant, as time goes on, the length of the fetus's femur will continue to increase, and weight and length will also gradually increase.
Many parents are worried when they see that their baby's femur length has not reached the standard value, fearing that their child's legs are too short. In fact, parents do not need to worry too much because the fetus will move in the mother's womb, so the measurement is not so accurate. Moreover, different fetal positions and variations in the doctor's operating procedures can lead to measurement data errors, sometimes even significant. Therefore, it is normal for the baby's data to differ from the standard value.
After 30 weeks of pregnancy, women are allowed to have an upper and lower 15 day error in the measured data. So when parents see that their baby's data is not standardized, they don't need to be too nervous. If there are indeed problems after re examination, you can seek medical attention to solve them.
