12 week scan tomorrow

Camilla
I have my 12 week scan tomorrow. It's for Down syndrome. I had to do the blood test but haven't done it yet so I am hoping they will still do the scan! But I am so nervous! As if all goes well and Bub is healthy my partner and I will be announcing it to everyone! And I will be telling my boss Monday. 
I am just so nervous I don't know why! I just don't know if I could handle bad news as I want to be a mum and this is our rainbow baby!
