  1. Hello Dear,

    Thank you for writing to us at MediMetry.
    If you have a larger than average baby, the ultrasound will apply the husky figures to the “normal” measurements. This creates error in that the baby will compute out to be further along than he or she really is. For instance, say you normally have eight and nine pound babies. Then your baby at 37 weeks will have bigger measurements than babies destined to weigh seven or eight pounds at birth. The computer in the ultrasound (ignorantly) lumps your bigger baby into the dates of big babies in the “normal” population.  Chances of error are increased in 3rd trimester. So don't worry, its absolutely normal.
    Hope this answers your query. Feel free to write back to us with follow-up questions.
