Hello, I would be happy to help you with your question.
The main measures of fetal growth (HC, BPD
, FL, and AC) are all in complete agreement. If the due date of 7/21 is within 1 week of your due date (+ or -) then the growth is perfect. There is nothing that I can see that is abnormal on this scan with regard to what you are showing me. Babies with Down's syndrome have findings such as lagging growth, shortened femurs, and other findingings that they obviously did not mention in the report. Finally, your recent viral illness is likely the cause of the rash
. It is worth talking to your doctor about this and ask them to draw blood work related to 'parvovirus'.
I hope that this helps and good luck!
