do i need to drink 1 ltr of water and have a full bladder before my 20 week scan? i made an appointment and the lady didnt mention anything about having to have a full bladder....
normally just 600 mls of water. they will tell you if you are full enough once they start the ultrasound. your normally over full than not full enough.
I'm pretty sure for my 20 week scan it was half a litre or as close to a litre that I could. Even then when I was waiting for my app they let you go to the toilet if really need be to release the urge without letting it all out. I was going to pee myself 🙈 haha
I got told to have 500mls
