I'm 2 months on diet, and I also started seeing candida in my stool just recently, and I know I was cleaning before cause I was also feeling better in that short time... so I guess candida in stool is only one sign of cleaning but not must...
Also don't be sure you are getting rid of all of it in only 1 1/2 months, better go check it for sure, cause if you stop diet and everything now it can come back easily...
