2-3 days without any movement is not normal by any stretch. It sounds like you have a chronic partial obstruction, could be a kink from adhesions, or maybe an anal stricture. But, constipation followed by loose, frequent stools often means that there is an obstruction and when the pressure gets high enough, loose stool comes around it.
You need to tell your doctor about these symptoms, and if you are taking any bowel slowers/fiber supplements, you should stop them until this is sorted out.
