At 20 weeks I had put on about 10kg's and I have now put on around 20 I'd say, I might weigh myself again on Tuesday. I don't actually 'feel' that huge which is strange although I know all the weight is on my butt and thighs! as well as my belly of course! I have not been weighed at any of my OB or midwife visits which I think is wonderful because if they aren't focusing on it then it makes me feel pretty relaxed about the whole thing. I anticipate that heaps will fall off after bubs is born and I'm breast feeding and when that starts to slow down I will start focusing on loosing the rest. Don't stress about it, it's the one time in a womans life when she can feel 10% sexy and glowing and beautiful while carrying a bit of weight around
