Hi!
I went for my 12 week scan last week and it was a shambles. I was in a room with a few others who got called in, people kept arriving and getting called in while I just sat there.
After I was 1/2 hour late and starting to get very emotional with a full bladder, my dp went and queried what was going on. I was told that there were 5 sonographers and mine had a broken machine, which is why I was still waiting and others were going in.
Anyway, ten mins later I finally got called in. The sonographer commented I had a very full bladder!
Hardly surprising!!
He did the scan, found the heart beat, but couldn't do the nuchal fold test as the baby was either on its back or front.
He rushed us off, think he realised he was running very late, told me to go to the midwife at 15 weeks to have a blood test. He also couldn't give us any pictures as he hadn't taken any 
Found the whole experience not as positive as id hoped for. Should he have offered me another scan to do the test? He said my dates put me at exactly 12 weeks so plenty of time.
