disqualified for having a calculator

Today i had two exams, chemistry in the morning and computer science in the afternoon. The chemistry paper was a calculator paper so i obviously had a calculator in my pencil case. I finish my exam and had to wait around1 and a half hours for my cs exam. i spent most of that time just destressing and getting some food. The cs exam come around so i grab my pencil case and go to my seat. i start doing my cs paper and about 1 hour in an invigilator starts looking at me and starts talking to the other invigilators. i thought it was nothing but gossip or sthmn but finally when i finished my paper one of the invigilators came to me and told me to stay behind. i was confused as i didnt do anything wrong but once everyone left the exam room they have told me they suspect me of malpractice and i have to write a report to JCQ or the exam board icr. they explained to me that the cs paper was a non-calculator paper and they saw me have my calculator in my pencil case. i tried explaining that i haven't even touched it but they weren't having non of it and even told me that i will be lucky not being disqualified from all my exams and they said they will write their reports but they made it sound like their against me. The non-calculator rule is mainly for paper 1 anyways, for paper 2 its mostly writing so i honestly don't even know where i would of used it. Please someone tell me what's going to happen like I'm so nervous.
