I Have Notice In My Feces For The Last 2

I have notice in my feces for the last 2 days that I have white ( shaped like a piece of a pretzel stick) and they are about 1/8 of an inch in length . Need I be concerned ? I just had a EUS exam about a week ago and so all is good with my pancreas gallbladder and common bile duct. Just still have the pain in my right side of my stomach area
