CO Poly re-up. Polygrapher said I had significant responses

I recently took a CI poly for FBI. At first the readings were not coming back clean so the menthod of me answering the questions changed to nodding my head. After answering all of the questions the polygraph stated that I had a significant response to a few of the questions that I shouldn’t have had and it has to be reviewed by qc. They didnt mention which questions in particular had this responses. I stated I told the truth through the whole process. Am I screwed?
