I was already overweight 76-78kg when falling pregnant, thanks to a miscarriage a year of trying and months of clomid.
by the time I got midway through my 2nd trimester I had gained 10kg's.
Um, I think we are twins separated at birth!! I was about 5kg lighter than you when I fell prg (70kg is the perfect weight for me for my height, puts me at a size 12 which is fairly slim for my build) but was slightly overweight thanks to clomid and ivf and probably a fair dose of emotional eating!!

I weighed myself yesterday morning and much to my horror I have put on 10kg!! I only put on 13kg total with DD so now I am a bit stressed.

I am also really worried that I have GD due to the extra weight gain and sugar cravings - I don't usually have a sweet tooth but my god your DH would be horrified at the number of 'whole' mars bars I've eaten this pregnancy!

I have decided to make some changes to my diet though - am cutting out all chocolate, reducing the sugar in my tea etc and limiting take away foods. Not that I eat heaps of it but probably more this pregnancy than last.

Fingers crossed neither of us have GD and lose the weight quickly once our babies arrive, I did last time so hopefully this time will be the same.
