First ultrasound tomorrow, scared to death.

Larissa
Hi all, 
I have my first ultrasound tomorrow (should be around 8 weeks 4 days) and as much as I'm trying not to freak out, I'm terrified that I'll go in and receive bad news. I had a missed MC in March, and although I feel very different with this pregnancy (all symptoms are much stronger including morning sickness), it's so hard to focus on the fact that this is a different pregnancy and it could have a completely different outcome. Those of you who have been through this sort of thing, how do you get through the anxiety of it all? I'm driving myself crazy here!
