I had the 18-20wk u/s today. My baby's measurements were all on track for gestational age - except both his lil femur bones. Apparently they are measuring about 2 weeks behind everything else. #-o Has anyone else had this?

Apparently it is sometimes a marker for Downs - but often doesn't mean much at all. I measured in a really low risk category at the nuchal fold testing and I'm "relatively young" (30yo) so I'm sure all is ok. I had an amnio today - so should know more info in about 2 wks.

I'd appreciate hearing anyone's personal experiences with short femur bones please.
