There are sooo many reasons why irregularity could happen this time around!!! Past diet, current blockage, the weather may be different then the last cleanse, you may be releasing something larger this time around, may have nutritional deficiencies this time around, a more clogged liver, a need for oils, yadda yadda yadda. All that really matters is that it IS and you have to balance that out. Just keep moving forward and diong what wokrs as it works. Cleansing isn't cleansing if you aren't having BMs!
