Ah! I too am on a shockingly piss-poor wage, thouh DH isn't on a bad wage, so, if the limit's 50k odd I might qualify for somethign too! Good news!
debs I had a friend that was expecting a 'George'...but got a 'Georgiana' and thought about 'Georgia'...so, well...there are possibilities! Well doneon the bargain hunting too! Good luck with the scan too. Can't wait for mine.
I'm a little not worrying at all as it's irrational and everythings fine, yeah, worrying. Yolkis had a very active Monday and Tuesday, and then only a few nerfs (literally 2 or 3) yesterday and only a few today, though I can feel some, what I assume is Yolkis (or it's the tapeworm again) squiggles right now. I've been feeling a littel bunged up (despite yogs and prune jiuce). The frequency is just sooo much less than Mon/Tues. I suspect Yolkis has just moved a bit further back, so I'm not feeling it as much, but grr!!! Nagging paranoia's there... 
As for food, I'm still at a net loss (2lb) for weight and am just so tired still I'm worried I'm not eating enough (as well as dizzy, but that's the 2nd trimester). MW wasn't that worried and said I was eating healthily, but didn't weigh me or ask very much. I'm probably eating less than prepg, but then I didn't have the healthiest diet prepg and that probably explained why I'm overweight. I'm blaming Yolkis' love of fruit and dislike of cake...can't be good for you, surely! 
20wk scans: from what I can tell, at 20wk scan if they seen anything untoward they ARE meant to tell you that there is 'cause for concern' and should call in someone to talk to you, if not, will get you an urgent referral (as in today/tomorrow). As far as I'm aware, that's it. Everything else is meant to happen at your 24/25wks appointment. Though if they're combining the 2 they will confirm the results of the scan and it would be at this point they'd give you the anti-D (unless you've had a fall/bleeding, in which case they should top it up regularly/give you it earlier), as well as talking about antenatal classes, birth choices (again) etc. They shoudl measure your bump too. But then I've not done one before...this is a combo of what my nhs book says and waht my SILs had...(one had her first Anti-D at this piont).
