Everything i've read says that the pill should be taken at the same time every day. Just how exact does that have to be? I normally take my pill at around noon, but today I was going to be in a meeting at noon, so I took it before I left the house, at about 7:30am. Yesterday was the first day of a new pack, and I took yesterday's pill around 11am. I'm planning on taking tomorrow's at around 10am, to balance out the times, but i'm not sure if that works or not. Am I still covered even though I took it a few hours early today, or should I use back up for a week?
