does anyone know what this is

Where is it? It looks like the beginning of stretch marks.

no the little circles lol that a scar from stitches

I'm getting some dark round spots on my butt similar to yours but I don't know what it is.

I thought I read somewhere that your skin can develops pigment issues (ie. dark spots) because of the pregnancy hormones. maybe that's what's happening?
