What Causes Lower Abdominal Pain And Pale Stool With Undigested Food?

I have had pale stools for about one week and lower abdominal cramp-like discomfort for 3-4 days. I have no jaundice and stool consistency and bowel movement regularity is normal. I have also noticed some undigested food in my stool (quinoa specifically). To my knowledge I do not have Celiac, Crohn s, IBS, etc. My mother had gallbladder problems. I am 27 years old and in excellent health. I spend 2-3 hours at the gym daily, do not eat processed foods, and have never drank or smoked in my life. Thanks@
