On the last day of week 4 (Saturday) - a day I was supposed to take the last green, sugar tablet - I mistakenly started a new pack and took the first white, active pill, which was intended to be taken Sunday. Now, on Sunday (today), should I skip a pill entirely and continue my white, active pills tomorrow (Monday) to remain congruent with the pack? Or should I continue taking the active, white tablets? If I did this, I'd be taking Monday's pill on Sunday, Tuesday's pill on Monday, etc.
