I've Had A Lot Of Red Flakes In My Stool

I've had a lot of red flakes in my stool the past couple of weeks - quite a lot of them inside the stool. No noticeable blood; just lots of these flakes. A bit of back and forth between constapation and diarrhea for several months as well. Some mild discomfort in the perenial area the past week as well. I've been avoiding red foods the past four days, but they're still there. Got a doc appointment in two weeks, but that seems like a long time away:
'Any ideas?

Thanks
