Blessed Herbs colon cleanse question

Did anyone on here do this cleanse that has had trouble with fiber and constipation? Every time I take fiber, my constipation definitely gets worse and also the Bentonite clay.. would this cleanse not work for me if I have this problem? I am encouraged by the pictures of what comes out on this cleanse but I'm wondering if this would work for me or not. Thanks so much for any responses.
