I'm sorry for your anxiety. I know first hand how nerve wracking waiting can be.
I have heard of long bone shortening in relation to the things you described, but I haven't experienced it. My daughter, Charlotte, was found to have many things wrong with her while I was pregnant. I found out at 17, almost 18 weeks and it seemed like an eternity to have the final results!
I also declined an amnio, which left the doctors baffled as to why I didn't want to *know* more. But for me, it was only going to tell us if she if really did have a problem or not, not how I would handle it... which we would find out sooner or later anyway. What an amnio would have done (IMO) is scared me so bad that I would be afraid of my baby.
So insted, I waited it out.
Because you say that you will love her just the same anyway, then do just that. Love her anyway.
If it turns out that your baby does in fact have health issues, you will be prepared to take care of them when the time comes. It may seem daunting and scarrey, but you will have had time to love her so much that you will see past all of the problems anyway.
When the doctors told me that my baby would be born (if at all) with deformities, Down's being one of 'em, I was so sad. Then as time progressed, I saw a little boy and his mom at the grocery store. He clearly had Down's... but you know what I thought? Wow! That mom is so lucky to have such a beautiful boy. Really.
When you are faced with raising a child with problems, or not raising one at all...it breaks your heart to think that you would not have them with you. PM me anytime if you'd like to chat. I'v been there.
