femur measuring small...concerned!

Ashuhleex

I had a growth scan done 2 weeks ago and the results showed that baby girl was in the 16th percentile and her femurs were measuring behind about two weeks. They did the scan because my fundal height was 4 weeks behind. I'm now almost 38 weeks (sat) and went to the doctors today. My fundal height was surprisingly 37. She said the baby was most likely just laying low when I was measuring small. The thing I'm concerned about is the femur length. She told me not to worry and that ultrasounds are not always accurate. But being in the 16th percentile...she is going to be on the small size I presume. Anyone experience this? Or have the same thing going on?, I know I shouldn't worry! Like my doctor said...but honestly who wouldn't! Thanks ladies!

I was told anything under 10% they start to be concerned. Sounds like you're fine. And like you doc said, measurements can be off, plus everything could easily catch up.

My last LO had femurs measuring in the 5th percentile, and they slowly caught up and he was born a completely normal size.

My baby's femur according to the u/s is less than 3 percentile. I will find out when its born if they are correct. The only reason they are worried with me is because its 4 weeks behind. But there is nothing you can do about it so try not to stress.

I was measuring 4 weeks ahead at 26 weeks so I had a growth scan...I was told that developmentally the baby was right on track at 26 weeks and that she was in the 27th percentile for size with "a small head and short little legs." This wasn't unexpected as DH and I were not large babies and are not large people. He has a small head and we both have short legs. So it makes complete sense that our kid would measure that way. I only measured big because the baby was high and breech and all balled up at the time...at my next appointment I was right at 30cm as expected.

If you are on track developmentally I wouldn't worry about it....you're probably just carrying a future gymnast or jockey like I am ;-)
