Yesterday, I Bought A Burrito From A Local Store. I

Yesterday, I bought a burrito from a local store. I found a staple in my burrito. I am afraid I may have eaten one because I woke up rushing to the restroom and had red stools. I also had some hot Cheetos which is why I wasn't too alarmed about the red stools. Yet, I've eaten hot Cheetos in the past and my stools have never turned red due to them. Now its been 8 hours since I woke up and I'm startingto feel Abdominal pain. What should I do? Should I wait a day or two to rule out the fact that the hot Cheetos caused it? Or should I go to the ER now?
