Stomach pains and not had bowel movement for a few weeks los i have no feeling as if i need a bowel movement apart from the pain?

Obstipation?: Normal bowel frequency varies from 1 every 3-4 days to 3-4 movements per day. Many "normal" people alternate their stool pattern within this range. What you describe is outside the range, but your prior baseline stool pattern defines how alarming (or not)your current infrequency may be. Ileus, blockage, ischemia is considered if fever, tenderness, distension, bleeding, vomiting. Get checked/help.
