It still doesn't feel real

I'm 5 weeks and 6 days today and I find myself overwhelmed by knowing there's a little person growing inside me. I'm also anxious after the loss of my first 9 years ago and temporary infertility for about 2 years, I am just in awe that this could happen now. I'm waiting to have our first scan and praying that everything is fine. The nerves are overwhelming me.
