How accurate are US measurements

Ana

Hi all, I’m a first time mom and was just wondering from moms with experience how accurate the US measurements were. I’m 36+5, baby is measuring 38+2, 7.4 lbs and 97th percentile in length based off femur and humerus. I don’t think I feel as bad with this information wanting her to make her debut sooner than later. Thank you all and congratulations to everyone!
