I came to know that at 37.5 weeks normal fetal measurements are BDP 91 mm , HC 336 mm , FL 71 mm , AC 336 mm. Where as my baby measurements are BDP 88 mm , HC 324.3 mm , FL 70.8 mm , AC 335.5 mm. According to previous scans my EDD was 20th Oct. After this scan edd was extended to 29th oct. Does it mean reduced in baby growth. I googled it and came to know that BDP and HC are head measurements, does it mean baby head is small or any abnormalities in brain development? Should I worry.
