October baby might be September baby

Had a scan done recently and baby is measuring 36w and 4d at 6lbs 1oz, original due date based off of last period is October 21st (34w) but they said my October baby might be a September baby. The growth scans due date is 10/10/2022. Baby is so low in my region that they couldn't get any pictures of baby's face. In the 94th percentile for size and expected to be a 9lb baby. Anyone else in my situation?
