Hi All, thanks for all your kind messages..
Lipstick, think you were right about the gestational diabetes theory. I had a retest this am, and everything was fine. Although I'm not on 4 cans a day (that is v. funny), I did have a can the day before so maybe that's it. I never drink fizzy drinks usually, but since the pgy, i've developed a serious taste for coke.
Tribpot - I'm glad your dh will be at home for christmas, so sorry it was all a waste of time. Must be v. frustrating for you both.
I'm still in non-maty clothes, but most of you are on no.2, i've been told that you are smaller on your first. However, the mw did tell me yesterday, that i had a 18 week bump or a v. big baby (i'm 16 wks). I'm only small (5 ft, size 8-10) so now i'm slightly concerned that i'm about to have a huge baby. And here was me thinking I was going to have a little 6 pound tinker. Fingers crossed they've just mixed up my dates..ha ha.
