Ways to induce a period??

Today is supposed to be my new period day, but I’m usually early by a day or 2 so I’m annoyed that it hasn’t come yet. I have a trip planned for next month that I really want to be period-free for, so I was wondering if any of you ladies have discovered any methods that help to induce your period? I know some say that exercise helps, but are there any other at-home methods out there?

Also, I haven’t had any sex in a few months so I’m definitely not pregnant. My body is just conspiring against me apparently 😒 lol
