Period on vacation?

Jaclyn • Realtor. Wifey. Lucky Lady.
I'm going on vacation on August 22nd and my period is supposed to start on the 23rd. I'm usually normal, rarely late. We are only going away for 4 days so I reallllyyy don't want to have my period the whole vacation... On the beach!! 
Any way that I can delay my period?? 
I don't use tampons.. I never even tried. I'm scared of them lol 
Help! 🙏🏻
