Hi Kirsty Lee,
It is sooooo normal to be nervous. I hardly talked for two day beforehand, I was so worried. We had the scan She said everything she seen was fine but she couldn't see half his face and part of his heart, so we would have to go back for another scan four weeks later. So I worried for four weeks, didn't talk for the two days before again, went to the scan and he was asleep on the wrong side. So she couldn't see what she needed to see. We spent 20 minutes trying to wake him up, then he woke up and moved so she got to see quickly what she needed to see then he went back in the other spot. He takes after his dad.

Let us know how your scan goes.
