Delaying your period..?

Hi! So I'm going on a vacation to the Caribbean in like 2 weeks and my period just so happens to fall on the last couple of days of the trip and I was wondering if there are any ways to delay your period for like a couple days. I googled it and found that apparently bananas and parsley are supposed to help. I'm not on the pill so I was looking for other solutions. Do any of you have any other suggestions that could help? Thanks!!
