Drinking water before 17 week 3D sono

Danielle

Hi everyone!

I am going for 3 private 3D Sonos so my husband can be part of this as my Obgyn does not alllow husbnads in. I have my first one tonight 17 weeks they say come with full bladder. I drink 100 oz of water everyday. The paper says to drink 33 oz an hour before and dont pee. I don’t even feel like thatspossible lol do they just say that much to make ppl think they need to drink more?
