Hi and
I am sorry for the loss of your baby.
Congrats on the BFP.
For me I would just try to think things happen for a reason. I know tons of people say that and it doesn't really help, but for me I try to belive in it for my own healing.
Lots of sticky dust

for that little one growing inside you.
You son is a cutie!
You can also check out the Pregnancy after Loss forum. Seeing as not too many of us here are PG you may be able to find more support there. You are very welcome to stay here though if you feel more comfortable. There are no rules as to where you can and can't post
Again Welcome and Congrats!
