Suggest Medicine To Delay The Periods

I am twenty-one years old, I weight 115 lbs and I have no medical history except for an appendectomy three years ago. I am in good health and am looking to delay my period because of an upcoming vacation. I have read about norethisterone and I was wondering if a doctor could prescribe that to me over the phone. I don't need an examination, just the medication to delay my period starting next week. Thank you!
