Is it really possible to induce a period?

I read online that it is possible to induce a period. You would do this if you had some major event that you would want to plan to not be on your period for. Online it says things like parsley and ginger and a lot of vitamin c? Is that a hoax or is it possible? If so, I would like to do it because I’m going on a chorus trip to Virginia beach and I would prefer not to worry about my period.
