Hardness above Csection scar

I havent really felt above my scar until last night while lying in bed. I noticed that its hard, above my my incision, about 3 inches across of my 6 inch incision.

Does anyone else have this. I'm 1 week 3 days post repeat csection.

Is this scar tissue? I plan on calling doc tomorrow, but wanted to see if anyone else has this.
