Bowel issues

I have been following my protocol and doing the intermittent fasting for 13 days and I am doing really well with a weight loss of 11lbs so far. (staring weight 150, goal weight 110). I feel pretty good except for being cold a lot of the time. My issue is that not only am I not having bowel movements (4 days since my last BM) but I am not even having the urge to go. So its not that I am constipated, but that I don’t even feel like I have to go. I am pretty sure my body is meant to dispel waste at more regular intervals than every four days. Any thoughts?
