Anatomy scan at 25 weeks

Rachel
I will be 25, almost 26 weeks at my anatomy scan next Friday because the hospital has been backed up. Just wondering if anyone else has gotten one this late. I'm also wondering if I really need to show up with a full bladder, as instructed. I know when the scans are usually done around 20 weeks a full bladder makes things easier to see, but I would think at almost 26 weeks they shouldn't have any problems finding anything.
