Embarassing problem... Anyone else?

My son is 6.5 weeks old. I have been having constant diarrhea for 4 weeks now. Has anyone else had this problem? Is this normal? I had a c section after 26 hours of labor and my body wasn't progressing.

I went to my OB about it and they sent me to a lab to have a stool sample done and those results came back normal today. I now have to go see a GI doctor. I'm hoping to have it resolved before I got back to work in 2 weeks. I'm just wondering if anyone else is or has had the same problem and what the outcome was?
