Super unsure and confused

I had to go to l&d to get checked out and they did an ultrasound of my daughter to make sure everything with her was okay. Well when they were doing the measurements of her femur and humerus the tech said she always double checks to make sure her findings are accurate. Well when she checked my daughters bone the first time it measured in the 8th-10th% which was fine because all my babies have been small and I’m petite. Then she double checked it and all of a sudden the baby’s bone was in the 40-50th percentile like wth so now I’m stressing thinking this baby is gonna be huge and I’ve bought all small stuff because my other two kids (my youngest right now being a boy) we’re both small should I be preparing for a big baby????
