I just got back from my 20 week scan. My baby's legs are measuring short. Like 2.5 weeks behind. He said everything else looks great. He didn't have any other concerns. Heart, brain, etc. all good. He wanted to see me back in a month but I couldn't wait that long so I will be seeing a specialist next Friday. I'm just so scared / nervous. Doctor also said that he wasn't concerned about Down syndrome and told me not to worry. Obviously, easier said than done. Anyone else have a u/s with short legs and turned out to be ok?
