C-Section Scar

I had a Caesar 15 and a bit weeks ago and I haven't had any problems with my scar til now.
I have a lump right below the scar on my right side. It is tender to touch... Could it take this long to get infected???

I'm going to call my Dr tomorrow to get an appointment but I'm kinda worried about it now.
Should I go to my GP or go to my OB that performed the Caesar?

I'm a little bit worried about it...
The past few days I did notice that it was a little more tender than usual, but today is the first time i've noticed the reddness and the lump.

It just seems like a long time after to become sore.

I would get it checked out to be on the safe side. Dunno about infection, is it a warmer patch of skin then the rest? Just visit your normal dr first and if need be then they'll refer you back to your ob. I wouldn't worry too much now but definately tell the receptionist when booking your appt that you are concerned so that they'll fit you in quicker than normal. Good luck and let us know...
