Terrified of anatomy scan

I’m 17+2 and the anxiety over the anatomy scan is creeping in. After a miscarriage earlier this year, I felt so detached from this baby during the first trimester. Now, after finally feeling excited, I’m starting to panic that something else will go wrong. Anyone else have these thoughts? Or know a way to calm your mind? Convinced I might lose it over the next 3 weeks..

Note: we had a “low risk” Panorama at 12 weeks.
