Everyone is different, they let me per before and during the scan. Don't "need" a full bladder, at least at my scans

thanks mommies!

Absolutely.

yes you have to have a full bladder when you get it done so they can see baby. I had to drink 42oz before mine

Yeah the only time you watch what you eat is before 1hr glucose. With that do not eat any white starch foods or anything with a lot of sugar. Just make sure you dont empty your bladder before you go in.
