So exited and scared!

We're having twins! But Is it normal to be scared more than excited when I go for my scans? I had a miscarriage last year at 8 weeks. I'm 9w1d today and I feel like I will worry until I'm in my second trimester. My doctor has me come in every week to make me not worry and everything looks great so far! I'm just scared. I go in again on Wednesday.
