Not sure about the asymmetric part but Blake was IUGR - was noticed around 30 weeks I think when my b/p went up. I was induced at 36 weeks, delivered naturally and he was 2.08kg and spent just under 2 weeks in SCBU. I was having scans every 2 weeks from memory and had a heap of blood tests ( I had 4 in one week
) and was referred to the hospital where I was under ob care but my m/w was still at the birth.
