I'd tried to lose some weight and wanted to get down to a "healthy" weight before I did get pregnant, but that didn't happen and I was about 78kgs, 8-10kgs more than what I "should" weigh when I got my BFP.

I was told by GP not to put on any weight during pregnancy....yeh right lol. I actually weighed myself yesterday and I've put on 8kgs in total up till now and by no means have I been strict with my diet, I try and eat healthy most of the time but the odd choccy donut & macca's somehow make it's way in there (ok more often than they probably should) and I don't do regular exercise, I try work it into my everyday running around etc.

I just figure your body does what it needs to to grow a healthy bub, whether it be use up fat stores or add some more.

I agree with Arimeh, everything in moderation & chuck out the scales - as long as you and bubs are healthy is all that matters.
