9 yo with few crohns symptoms

I took my 9 yo son to his Dr. because he has had a weight loss (4 lbs) in the last year and a decrease in his appetite also tired alot. Labs show anemia so we were sent to a hemo Dr. she did a CT that showed thickening of the bowel she sent us to a GI additional labs and stool sample lead to Crohns. We have a endoscopy and colonoscopy scheduled for next week (biopsy). My problem is he has NO stomach pain or loose / bloody stools. Aren't these the primary "symptoms" of Crohns?? I'm confused and really worried for him!! Any insight you may have would be GREAT!!
