thanks for all the support folks - it really helps :)
I had my GTT yesterday - as Mamma said, they're not too bad! The tropical squash stuff is pretty foul, but bearable. I had my bloods taken (from the one poor scarred up vein in my arm that actually gives out any blood to needles!) and they also did my BP/urine check as my hands/feet/ankles have been puffing up a bit (all normal). I got my results this afternoon - the GTT came back completely normal - which is great! But it does mean we have no explanation for the sudden growth of fuzzy!
carlita Between the last 2 scans (a mere 14 days apart) fuzzy has put on 28oz! That's 2oz a day! If fuzzy kept this rate of growth up, he'd be about 11 pounds at 40 weeks! (and would have one hell of a belly!!)
The biggest concern is the sudden shooting up of the abdominal circumference - he'd been comfortably hovering just over the 50th centile on this, the scan before this one he jumped up to about the 80th, then at this one he was literally off the scale (you get this little illustration on your scan report - imagine a 1.5cm tall capital I laid on its side, the left end is the 3rd percentile, the right is the 97th - a little line scores through the middle to show the 50th and they put a little diamond on the line to show where your result sits. Fuzzy is about 3mm off the right hand end of the "I"..) Usually a sudden jump in abdominal circumference is caused by gestational diabetes, hence the urgent GTT. As that is fine, I'm hoping it's just sonographer error, as it's a bit odd otherwise.
There's no history of big babies in my family and i'm petite (5'3" and usually a size 8-10, very much not a curvy wide hipped woman!) so an 11lb baby would be pretty damn hard to deliver! Not least with the restricted range of motion I have in my hips/pelvis!
Obviously I'm really pleased that the GTT has come back fine - but i'm a bit unsettled by fuzzy's growth! The biggest concern in this pregnancy was that fuzzy would be small, due to my IBD/meds - I never expected to be worrying about having a big baby!! 
I guess this is the downside of 2 weekly scans - you get lots of information you wouldn't normally have and it's very easy to worry/overreact! Fuzzy may slow right now on the growth front again now - growth isn't always even and steady, even if the growth charts expect it to be!
I'm back up the hospital for my next BP check on Monday, so will talk to them then. I have another scan a week monday, and an appointment with my obstetrician straight afterwards, so will see what that brings!
In the meantime, my MiLs oncology appt has come through for next wednesday, so we should have some idea of what's ahead of us before we see my obst, which is good.
Davina have everything crossed that things start happening for you soon! I hope your last day at work is going well! Am amazed and so impressed that you have worked right up to your due date!! Compared to my sloth like existence on the sofa you are simply amazing!!
mamma I am right with you on the hormonal melt downs - I am all over the place! It's no fun feeling low/weepy and upset for no apparent reason! I've taken to watching my er boxsets - then at least I can have a justifiable cry! 
(although have had to skip one or two of the more upsetting episodes!)
bun mmm, fairy cakes! You and your DS are quite the baking gods!! 
Thanks for the offer of cake/company! If I ever get a day to myself I may well give you a shout!!
carlita Fyfe sounds so lovely - please do post a photo! I'm really looking forward to seeing your gorgeous boy!! Really pleased for you that everything is going so well!
So sorry I can't manage a proper update - am really missing properly partaking in the thread! I am lurking and reading when I can - next week is going to be crazy but I hope I can find time to check in! If nothing else, I want to know if davina goes into labour!!
