First U/S in an hour - anxious

Ta
Finished chugging my litre of water and going to get ready for my first u/s. Am 7 weeks 2 days and really scared that they'll find something wrong. DH is telling me not to get attached just in case but too late haha! Crap starting to cry writing this - damn hormones!  
Update: we saw the heartbeat and I started bawling, as I have never seen before. I'm in love 💕
