could be many things given what you've said or what you've not said. but as to blockage I would say if you are passing stool its not a blockage, unless its only tiny drips and dribbles in which case you might have a partial blockage. but to my mind a blockage's hallmarks are bloating, no stool, no gas passing, waves of mounting pain with increasing bloat. the waves of pain are the peristalsis being stalled and fighting to get past the blockage. ultimately the pain will crest to the point where you feel vomiting might relieve the discomfort and sometimes that in and of itself does alleviate the blockage. but the pain will be so severe that you will likely name and seek the help of every known deity, in every language.
