I've never been pregnant before, this is my first. What do bumps feel like? I'm 16 weeks, and although I was skinny, I still had a little belly. When I sit down, its squishy. But when I stand up, its hard, but not too hard. If that makes sense. I feel like I can see a bump coming because it pops out a little at the bottom, but I cant be sure. Any help?!
