MrsE I gained weight while bf too. I was straight back into my ore pregnancy jeans within a week or birth and they still fit now, a year on 
I have a theory that for me a lot of weight gain and loss is hormonal. I ate like a horse in my last pregnancy but was all bump, and when I dropped to two bf a day I lost half a stone overnight.
I'm also worried about GD this time. I may have had it by the end last time, although as dd was under 10lb I'm not automatically in the at risk category. I might request a GTT this time although our local midwife is a crap unfortunately. I suspect I'm heading for a 10lb baby. We had problems with low blood sugars last time and I'd rather be prepared this time around. I'm also irrationally terrified of shoulder dystocia. I never thought is find this scarier the more times I did it.
Good look to Jenny and your booking app this morning.
My symptoms seem to have temporarily vanished. I'm sure this is normal.
Sorry. I'm a real bag of fun this week, aren't I?! Hate to whinge. Will have a word with myself.
Thinking of those struggling with half term, sickness, and fatigue. Especially thinking of Notsoold. Hope you're doing ok lovely.
