Suggest Medication To Start Delayed Menstruation

My period is a week late. I have tried strong ginger tea, parsley tea, high doses of vitamin C (3000mg), hot showers for 3 days but didn t induce my period. I didn t even get cramps. It s because I don t usually cramp a lot before my period, maybe that s why. Anyway, I also used heating pad for 2 hours today. I have a feeling of period but it doesn t come. I m not pregnant and it isn t even a possibility. So what can I do to induce it today? I need to since i ll be traveling in 2 days. Does ibuprofen help to induce it? Cinnamon tea? or anything else? I m desperate please help.
