I'am going to be a daddy!
My wife and I lost our first one and so I know exactly how it feels bro. After looking into it and word of mouth, it is pretty common actually. Odd because you never really think about it until it happens then you. Then you find out from all sorts of people / couples that is happens a lot.
We ended up having two very healthy kids afterwards. Dunno. Natures way of clearing the way?
Hang in there bro. Best wishes from a guy whose been in your shoes.
