Doubt on Malpractice

Is there any chance that invigilator doubts you and checks you thoroughly but finds nothing but put malpractice later?

After doubting they couldn’t find anything (and honestly i was not carrying anything or cheating ) They didn’t changed my answer sheet and also no form signed and no photos of id clicked…is there any chance that they will write above my paper “malpractice” or don’t send the paper to professor🥲
