I Have One Mifepristone Pill And 4 Cytotec Pills, There

I have one mifepristone pill and 4 cytotec pills, there were sent in a package but did not come with instructions. How do I know if the cytotec is oral or vaginal? How long do I wait to take the cytotec after the mifepristone? Will the pills still be affective if they are expired by a month? Will they be more affective if I am only 4 weeks gestation?
