Welcome Buzz you'll have everyone in the UK jealous of your multiple scans, they're pretty tight with those on the NHS!
PJen can't help you with the scan issue but I know measuring small for dates has happened to others on here. As far as weight goes, I've put on about 6 lb since finding out I was pregnant (am 13+1 now) but that is largely due to the fact that I have been eating like a horse.
Have agreed to participate in a Tommy's study being run at the hospital here which involves 3 hospital visits and some extra blood tests but does get me 2 extra scans (28 wks and 36 wks)...my ears pricked up when I heard that
Kawaiiko haven't told work yet, want to leave it till about 16 weeks I think. Still wondering how best to tell my admin who lost her baby last week at 15 weeks....reckon telling her first (after manager) and privately is probably the best way to go. She's back at work today (amazing given she delivered on Wed last week) and actually seems to be doing pretty well.
Boo in awe at how you've steeled yourself to get pregnant again after what sounds like a complete NIGHTMARE the first time around! Glad to hear that your DH is giving you the support you need this time around. My DH is, on the whole, being very good although I know he is sometimes sceptical when I complain about the "invisible" signs of early pregnancy - nausea, tiredness, breathlessness etc. Would be better if I was puking my guts up and passing out all over the shop I think I think it will be more real for him when I am visibly pregnant. Doesn't stop me complaining though
Loopy not sure about spontaneous hayfever affliction later in life! I know I had it really badly when I was a teenager but have grown out of it to a certain extent over the past 10-15 years or so. Whether the same thing could happen in reverse I'm not sure! If it gets really annoying you could always slip some Piriton, as that would help the hayfever and also a runny nose caused by a cold. It might make you drowsy though so possibly not the best when you have 3 to look after!
Re crazy dreams, I had the mother of all dreams last night....but will not disturb your sensibilities by sharing, doing my best to forget it! Nice to be able to attribute it to pregnancy (phew).
