20 Week Scan

Had mine last week. They said by 20 weeks your far along you don't need a full bladder x

The more hydrated you are during the week, the clearer the scan but you don’t need to go with a full bladder x

i didn't have that full a bladder and the scan was harder as a result, so i would suggest still fill up a bit but no need to go extreme! other than that nothing to prepare. they might ask you to wiggle around a few times if the baby is in an inconvenient position.

I never go with a full bladder. I just have a glass of water before the scan x
