Am I doing something wrong>?

I have always had 1 bm a day. I started taking the PB shakes 2-3 times a day fora Bowel Cleanse and now I am only going 1 every two days. I got on the scale and I weigh three pounds more! I need to lose weight so that does not help!
Why is this so? I thought psyllium to help with getting things going. I thought with the shakes I would be seeing the MP. I have been doing the shakes for 7 days now and feel so bloated! I must have so much inside me.
Am I doing something wrong? I am exercising every day, more than before and am eating so much better too.
