Hi Jess
GOOD LUCK for tomorrow, def sending you good luck vibes. I think everyone gets nervous before a scan, but I am sure you have nothing to worry about - think yourself lucky you didnt get M/s too badly!!!!
I am sure you will find the scan amazing, you can see a lot more than in earlier scans.
Your DH will love it too, it is a special time so try not to worry and enjoy it.
Hope you have a happy and healthy pregnancy.
