Suggest Medicine To Stop Periods

Hi, i'm 23 years old, today is my fiancée's birthday and i was hoping to sleep over at his place. But i have a very bad luck and i got my period about an hour ago. I cannot disappoint him as he reserved a room in a hotel and everything is perfectly arranged. I want to STOP my period now, i don't care if i get it tomorrow but not today. Is there anyway to do that? any medicine? or any herb? anything please.
I live in the middle east in United Arab Emirates, please give me a medicine that i can purchase here please. I'm so desperate for your help

Sincerely,
Lara
