I'm currently 29 weeks pregnant with my first baby. At the 20 week scan everything was normal and all measurements within 50th-60th percentile. I went in for reduced movements at the weekend just gone and ended up having a growth scan. This scan found that the femur length is now in 5th percentile whilst everything else is still 50th-60th. They want to do a further growth scan in 2 weeks but in the meantime I am absolutely worried sick. Google suggests Down's syndrome or Dwarfism. Has anyone had a similar issue and if so what was the outcome?
