They told me not to because the scan is so long. They just said be hydrated

They would give you instructions to. If they didn't, you can call and ask. They gave me instructions to have a full bladder for mine. It makes the image clearer

I had a full bladder & the ultrasound tech told me to drink Orange juice before hand as that makes baby move more! I hope this helps!

Nope. I didn't. You are far enough along.

I had to. My office gave me detailed instructions on when to pee and then how much to drink an hour before my appointment and not pee. I would call your doctor to confirm. You wouldn't want to have to reschedule if you were incorrect.

Mine is at 9:00am and they only told me to make sure I eat breakfast since it will take a while. Last time I went in for my NT scan they told me to have a full bladder but mine was actually too full and it made it harder to see the baby so I heard the best news all of that day so far - go empty your bladder - lol!! My plan is to eat a healthy veggie and protein based breakfast and then drink a small glass of watered down juice about 30 minutes prior
