I had my baby 2 weeks ago. Now I’m pretty much back to having a flattish stomach and I have no stretch marks. However, where I had the bump, the colour of my skin is much darker than the rest of my body! I am an olive/ light tan colour normally but this part of my belly is a dark shade of brown! There is a clear demarcation under my boobs where this colour begins. Is this going to go away? Thanks
