Short femur?

I just had a 33w growth scan and while baby is following his growth curve accurately, I noticed his femur is charted much lower than the other body parts. The dr didn’t mention this (which I assume is a good thing) but I noticed it in the paperwork after I left. Has anyone else had this on a growth scan? I’m hoping femurs are just hard to measure at this point in gestation 🤞🏼🤞🏼🤞🏼
