What Causes White Specks In Stools?

Within the past two to three days, I ve noticed white specks in my feces. I m not sure what it is or why I found them but after doing research it s obviously not right, I m just debating whether I should wait a few days to see if it goes away naturally or rush to the doctors to try and see what this is exactly. What would you think it may be? I m not experiencing any type of symptoms such as diarrhea, nausea, upset stomach or anything. The only pain I feel is my back which I m sure is due to bad posture over time, and besides that an occasional pain in the back lower-left side of me back about a little more than halfway down my back, not on the spine though.
