Reported RE: Mechanical Pencil

I took my SAT today in England, i used a normal pencil for all my SAT bubble multiple choice answers, but a mechanical pencil on my essay. The proctor saw this and said she is reporting me, I am super stressed because if my scores get cancelled (or fail to scan) I wont have time to retake the SAT and the SAT subject tests before submitting my application for 2017 entrance.
Has anyone ever been reported for this before and what was the outcome? I’d appreciate if anyone could please put my intense nerves at rest.
Thanks a bunch, Max Raven.
