Update! What wrong with my c-section scar?

(Tried to crop the picture to my best ability so no vajayjay) I'm 6 weeks pp last week I noticed this little white spot and thought it was puss (gross) so I washed it with the special soap from the hospital and just kept an eye on it. It hasn't gone away and its leveling out with the scar. I picked at it and it chipped like paint! WTF?! Should I call my OB Monday? What the hell chips like that? It's hard too!

Note: I should mention when poked it stings like hell and my jeans hurt it too. Really any presser around in hurts like heck.
