in, on, over the next several days? | WordReference Forums

Hello all, May I know what is the difference between: "in the next several days" "on the next several days" "over the next several days"? If suppose I have an exam tomorrow, another exam on the day after tomorrow, and another exam on the day after the day after tomorrow, which one should I use?
