thanks everyone
nypage, my scan wasn't very long either, the regular part of it was maybe 20mins. little boy was very co-operative for the sonographer!
as for the full bladder - I wasn't told I needed one, and as it happens I definitely didin't have one because I went to the loo beforehand. guess different scanning machines have different requirements? I needed to have drunk a pint of liquid before my 8 week scan though.
I also had my cervix measured today in an internal scan (and was told to go empty my bladder for that, I managed to squeeze out a couple of drops!). all was fine there, too, long and tightly closed, 34mm. so no risk for pre-term labour, thank goodness.
it all feels so much more real now. like before I was pregnant, ok, and having A BABY, ok. now this unknown baby is much more known to me! I know he is a boy, I have seen him a lot more than I already had... because I know he is a boy I can picture him in my family, picture my son with a baby brother - this is something I couldn't do before, just think of Adam with A LITTLE SIBLING, but now I know he's a boy I can get past tiny babyhood and think of them sharing a bedroom when they are older, playing football together, that sort of thing. It all feels so much like it's really happening. I felt this way last time, too, like the baby was some unknown entity and then it became my child, my little boy. it's really nice. I thought I'd be more disappointed about having another boy as we'd have liked a daughter, but other than a little pang, I feel fine and excited, and SO excited about my boy having a little brother. want to go shopping tomorrow and buy a little something for him, though. don't want to think that everything he has is a cast off.
