Deancey, my first pg absolutely wrecked my tummy *blushes*, I put on nearly 40kg. Going from 45kg to near 80kg's..
I never got any fresh stretchies from the next 2 babies but started going to the gym, got superfit and back to around 50kg and I still had the skin hanging down over my cha cha. I was doing 100 sit ups a day and that didn't help either.
I had a tummy tuck 5 years ago and now I am praying that this pg doesnt' ruin my tummy again - almost 30 weeks and no sign of stretching yet .
