does anyone else have a "dip" in their belly?

I have this dip right where my belly button is. Yes, I was overweight prior to pregnancy so this could have something to do with it. I'm 15 weeks and when I lay down it becomes more rounded and the dip sort of evens out. But when I stand up there's a noticeable dip if I'm naked or wear something form fitting. 
I know it shouldn't bother me...but it does. 
Anyone else have it?
Does it bother anyone else?
I also only have stretch marks on one side. I have an ugly side with stretch marks and scars. And a pretty side. Lol.
