Miskate, tell her you're pregnant, what's her excuse?! Or even, 'Oh yes, I'm so glad it's healthy to put on weight during pregnancy, if I wasn't pregnant I'd feel like...' and give her the up and down eyeball. With a snide smile.
Or just sit on her. No warning. Just go for it. 
I'm having a rather stressful morning. My designer has upped and left the company I outsourced my marketing project too, so now have to go in and brief new designer and get him up to date and back on track before the deadline whooshes past. Plus DP failed to do anything useful at all this morning - I even gave options, damn it! 'Please would you either empty the dishwasher, put away the clean washing or put the wash from the machine on the line.' Now have two loads of washing to somehow do today while I'm at work, some of which is stuff I would have quite liked to wear on my holiday! Hmph. Men suck.
Weighed myself this morning and I am up to a whole 58kg. That's 1.5kg up on my pre-pregnancy weight. Given I lost a fair bit (about 8 or 9kg) through the MS period, I think that's pretty good. Argh, I wouldn't worry about it if the flipping hospital MW hadn't started making clucky noises and telling me off! Just shut up! 
MrsD, I am slightly worried about asking how you found out a vibrator makes good headache relief...? 
haven't, if you're happy it will have been stored/prepared in a hygienic fashion, go for it! I'm planning on eating plenty of seafood in Lanzarote!
