I have an important holiday coming in 7days, I've never been on contraceptives of any kind in my life but I need to delay or prepone my cycle depending on which of the 2 is more doable! I need help asap. I've been reading that some ppl who took the "morning after" pill experienced delays so I'm wondering if i should attempt that since i have 7 days to go but i need my period to be delayed by a week or if preponed it needs to be in the next 24-48 hours.

Please help
