baby's femur bone bowed?

Hi ladies I just got back from my high risk ob appointment today and I got some unhappy news. My baby is measuring 22 weeks instead of 25 and she also pointed out that her femur bone looks bowed. Does anyone have any experience with this? She said everything else looks fine Except my placenta looks a little bulky but could be due to my high blood pressure. I have to have blood testing done for abnormalities now I just hope to god maybe the ultrasound just made her bone look like it was in an awkward shape.
