Thanks for all these additional details.
I am sorry to hear about your problems.
Well, such change in stool color along with abdomen cramps, can be related with problems with the bile duct.
In such problems the bile is not added to the stool and this result in pale color of stool.
Bile actually is responsible for giving normal color to stool.
In can occur due to-
-strictures of bile ducts
-stone in gall bladder
It can occur from Inflammatory condition of intestines (colitis), Irritable bowel syndrome, bacterial infection.
To make a diagnose, you need to get these tests done-
-Complete blood count
-Stool culture test.
-Liver function test and Ultrasound of full abdomen.
You should not ignore this, and please get it evaluated from your doctor.
Management would be advised after clinical evaluation and tests.
Please see your primary doctor and get it managed.
Hope this helped
