Is there any way i can delay my period that is due in one weeks time without using contraceptive pills?

No: Humans do not control their menstrual cycles by thoughts, by foods, by supplements, or by any other natural means. If that were possible, women would be able to decide when to have or not to have menstrual cycles, without using hormonal medications. Controlling menstrual cycles with merely desires, foods, or supplements would be very convenient, but life is not that way.
