Pill Problem!

Samantha
Hi everyone!!
Having a nightmare, booked a holiday to Cuba on the 30th for 14 days, only to realise I start my period on the 30th!!
My period is usually 7 days long and I really do not want to deal with it whilst I'm supposed to be relaxing! I especially don't want to be on my period for a 10 hour flight! 
SO, I found a sheet of my old (in-date) pills, so I'm thinking, should I start taking them? Will this push back my period to the end of the holiday?
Thanks in advance girls! 💘
