I am so sorry to hear of your heart-stopping result. I know I held my breath when the doctor came in to give me my results. I can only imagine what you are going through. I pray all will be well with your little one, as well as yourself and partner.
I don't have any advice to give, but I did have a question that stuck with me from my doctor. When given the option of doing the Amnio, she asked my husband and I the following question: "What would be worse for you? 1. Doing an amnio, finding out the baby was 'normal' and then losing the pregnancy due to the risk? or 2. Not doing the Amnio, delivering and finding out the baby has something that could have been diagnosed early on?" It's a cold and blunt question, but it forces you to look at your personal views and your own life experience. My OB said that if you look to the future or your present situation and you just cannot see yourself raising a special needs child, then you may want to consider the Amnio, despite the risks. It's a choice you have to make...I will pray for you as you make it.
I got the bad news today from my NT test. I have my blood tests Thursday. Good luck.
