I Have Weird Circular Spots Along The Sides Of My

I have weird circular spots along the sides of my abdomen. They are sightly brownly pigmented (not much). They do not itch. They do not hurt. They just keep accumulating as time goes by. This has been occurring for a little over a month now. They have a slightly softer texture to the rest of my skin. I have a feeling this is Pityriasis Rosea but I want to make sure it isn't anything else.
