I'm so sorry that you're having to deal with this news.
There are just so many worries when we are pregnant > 40. I am very sorry to hear that this is now on your plate and no doubt dominating your mind. BUG HUGS.
Third term US measurements are not as reliable as those taken earlier on... so it is VERY likely that everything is OK.
What does your doctor say now about your odds?
P&PT that everything is perfectly fine!
Good luck on a happy outcome. I know for me none of my third trimester u/s gave an accurate weight. Two days before my 3rd daughter was born they gave me a weight estimate of 8 pounds but she was 10.3 just 2 days later.
Try not to worry because it certainly won't change anything.
Hang in there!
Just a quick note now that I am home and back on duty to let you know that I have been thinking about you and praying for your bean. I hope that everything is going well and that a safe delivery is followed by a happy baby, who is healthy of body and mind!!!
Please keep us updated. We are all rooting for you both!
