Yellow stool and hunger pain? Its own?

So since few weeks i was having stomach discomfort(hunger type pain) and nauseous feeling. I also have mushy stool and it was light yellowish as well. Now since a week i am on rifaximin 550, my stool has become solid and normal, the stomach ache has almost gone and i felt nauseous today a little bit maybe bec i worked out legs in gym... my question is why my stool color still yellow? I have done cbc, lft, kft, thyroid everything, all normal, i am worried about cancer? Please help me, attaching an image to show color of poop. Will it resolve on its own? The stomach discomfort i mentioned, it was not ache, just mild persistent discomfort, which goes away(most of the times) with farting or burping or after eating. I am scared :(. Please help me. I am taking probiotic capsule as well prescribed by the same doctor...
