Frequent bowel movements, cramping with no period yet, a few days late, tubes tied over 5 years ago?

Question?: If your tubes have been tied there is very little possibility that you are pregnant. Frequency of bowel movements would not necessarily have any relationship to your being pregnant if you were, and any bowel problem may be responsible for delaying the onset of your period. You can always get a home pregnancy test kit and check a first morning voided urine. Good luck.
