Thanks everyone, I like to know what to expect with these things.

I'm having the scan partly because I've been bleeding a little and I'm worried, so the doc thought it was a good idea, and partly because my husband is about to go away for a month.

That means he'll miss my 12 weeks scan and the first meeting with the ob. I want him to see something that he can connect to, so he feels the baby is real. Also he's going to be seeing his family overseas and of course we want to tell them about the baby, but not if anything looks to be wrong at this stage (it would be awful to tell them and then have something go wrong, somehow worse than if we lived in the same part of the planet). His Dad will be so happy (elderly guy, we are his hope for grandchildren, etc), but I would hate to get his hopes up for nothing.
