Something seems to be up with my baby. The past few days when I handled her, she felt different then when I first got her - like more squishy almost.

Today when I was trying to get a tail pic, I realized that her skin seems pretty loose. Like, I can grab a piece and pinch it together with my fingers. When I took a closer look at her belly, there was this weird dented/folded line down the middle. Also, i noticed when I run my fingers upwards on her belly, I can feel a distinct, rough edge to some of her belly scales. I can't remember if it was always like that or not.

Is something wrong??
She's eating fine. Could it be a shed problem?

I got a pic of the belly wrinkle:
