Plus size

I'm about 5'9 and 250lbs. Now most would think this is big but for me this is the smallest I have been since I was about 17. Since September 2014 I have lost almost 130lbs, because of this I have alot of extra skin so when I'm standing you can't even tell I'm almost 6 months pregnant but I did start taking pictures while lying down. In a matter of 3 days I have noticed a massive change in my stomach, its very hard, moved up and I no longer have a crease where I did. Here is a before and after of my weight loss and my belly laying down. Does anyone else notice the change? The top belly pic was 19w2d the bottom was just now 19w4d
