worries
I know it can be so hard especially after a m/c not to worry! I lost my first baby after a car accident I was newly pregnant, but I still felt the full emotion of my loss. I still think of my baby in heaven.
My advice would be to relax, enjoy this precious time that you have. You are pregnant, you took a test and it was positive, you probably even knew or had an idea that you were before the test said positive. For now that is all you know. Try not to look into every little thing. Focous on what kind of birth you want to have, what sex you think the baby is, how this is going to be such a wonderful change to your and your family's lives.
We don't have control over this, just trust

I'll pray that you will have peace! You are already a great momma, putting so much thought and energy into your new baby!!
