Can you do this too

With your belly? When I lay down I can squish my belly all over it’s not tout anymore and the skin wrinkles up especially lower belly and I’m wondering if this is a sign that I’m going to have a lot of loose skin/sagging skin or that wrinkled up look after I give birth. I have gained a whole lot of weight these 9 months but the rest of my body is tout and I can’t squeeze my skin up like this. I suffered from body image problems before I got pregnant so I am worried about what everything will look like after but I want to be prepared for the worst so it isn’t such a surprise...
