Not to be a downer, but I am still having some fear/worry

I am 31 weeks exactly with my first child - a little girl. I still can't shake the fear that I might lose her. Does anyone know the chances of stillbirth after this point? Am I the only one still this nervous? I'm trying to find a way to not stress about it. I've been trying to stay busy until she is here and safe in my arms, but I can't seem to shake the worry!  I know this post might seem ridiculous, but I thought maybe some other moms can relate or help ease my mind?
