From my own experience I have had 3 major bowel obstructions ending in resections and not once did I have a fever. If the pain is there and the nausea turns to vomiting I wouldn't wait a couple weeks. If you really want to wait it out try clear liquid diet for a couple days and increase to full then soft. If you are still unable to tolerate it you need to be seen by your Doc or in the ER.
Hope you feel better soon.
