Hello, I am just concerned about my baby s fetal biometry. At my 19w u/s the measurments were BPD=4.52cm, HC=16,08cm, AC=14,23cm, FL=3,18 cm. The FL/BPD ratio was 70%, which is lower then the normal range (71-87%). EFW 305g. I had an u/s at 22w2d the measurment were BPD=54,4cm, FL= 41,4 cm, AC=17,3 cm. EFW= 501g. I need to know are my baby s measurments allright? I m concerned about FL/BPD? Do I need to be? Thanks, Mary
