Tomorrow is my 20 week scan. I want to be excited, and I am, but i'm also petrified! I was really silly and Googled what they look for and the problems they could potentially find. Now I can't stop worrying about my little one. Also it's been forecast to snow overnight - Aaaaghhh!! Where I live the council aren't too worried about gritting the roads, and the whole area pretty much comes to a standstill when there's snow. That's fine usually - Not when I have a scan though!!!!! Any reassurance would be gratefully received!!
