I'm sorry your Dh is wanting to wait Michelle. I run into some of that with mine. Don't take this the wrong way, (I totally think you deserve and can't wait for you to have another child!), but I think if we had a living child, my Dh would be acting the same way yours is. I hope you know what I mean, you are not alone in the way your Dh thinks.
Even though my blood draw the other morning went well, I still had bad luck that time I was in the waiting room. I could hear someone's baby who was in for a baby check behind me gurgling. And I was thinking I should bringing my baby up hear to be checked and not having stupid blood tests. Argh. So it does still hurt to go back there.
I hope you get that BFP soon, before you even go to see the RE!!
