Good luck.. The 20wk scan is so exciting.. I didnt need to drink any water for my 17,18,19,20 weeks scans.. Had a few problems on my LO pregnancy last year so had loads of scans.. Only had to drink water on 12 week scan as babs is so small..
Dont drink much as in the big scan they do so much pressing down to get the right angles it will just make you want to pee!! Good Luck
