Ok, so I normally hate to do this - post questions before I talk to my doctor - because it's almost always coupled with a wild irrational google search as well. So, I'm not thinking 100% rationally but I'm hoping to get some reassurance from this lovely group.
I am 17 weeks 4 days today. I went this morning for my "18 week" ultrasound. Everything looked great, the heart, brain, palate, kidneys, nuchal fold was within the normal range... Images were amazing - the 3-D shot was something I never had with DS so we were in awe. Baby was moving and yawning and pretty darn cute.
However, apparently the femur bone was measuring 1mm short. OK, so I didn't think to ask what it was measuring at... And I also didn't understand what it was being measured against - could the "shortness" be due to me being 17.4 rather than a full 18 weeks? How significant is 1mm?? The Dr doing the scan said it was probably nothing since the other measurements were normal, but a short femur is a soft risk factor for Down Syndrome.
Yes, so of course I'm in a tizzy. I mean, I hear the rational voice in my head saying "1) you aren't even 18 weeks yet and what's 1mm too short anyway, and 2) all other measurements are normal, so relax". My gut tells me to relax.
But I'm still totally freaked out.
I don't know if anyone else out there has had a "short femur bone" for their fetus... I did some searching on the broader community pages, and I know I'm not going to feel better until I talk to my Dr and probably have another u/s in a few weeks ... still... any thoughts much appreciated.
