Yes, so if you don't want to have your period, just don't go to the toilet. Hoped this helped :)
If you start your periods in school get a friend who has started her periods and ask for a pad - she should keep pads in her school bag 24/7. If you don't have a friend who has started her periods or has no pads, then either tell a trusted adult/teacher, Or if you don't want to tell anyone in school just go to the toilet and grab some toilet paper and place onto your knickers. Then tell your mum when you get home and she will buy you some.

You can induce your periods if they are due or late, but nothing you eat will make your periods start early.
