Has anyone had luck with pushing their period back a week or getting it a week earlier?

I’m going on a vacation and I’m literally supposed to have my period that ENTIRE time!

I don’t wear tampons. I thought about it, but it still makes me nervous that it’s going to leak in the pool 🤦🏻‍♀️

So I’m wondering if anyone has pushed their period forward or backwards a week? If so, how?
