Where should I start???

bo

So im starting a new pack of bc. But im confused on what day should i start because on last month's pack i lost 1 pill from i think week one(ex; Wednesday) so i took the Thursday one. So im 1 day ahead of my bc pills but. Now that i got a new pack i dont know if i should just start the Sunday week 1 or take the friday week 4 pill?
