Struggling with my post partum tummy.

I'm one week post partum and my tummy has definitely gotten smaller since having him but I think it looks really weird and gross. I feel like I still look pregnant and my tummy is such a weird shape now :( is my uterus still shrinking and everything going back to where it belongs or is this what I'm going to have to work off. I don't mind being bigger but it's such a awful shape :(
