Lost pill, when to start new pack?

[sleightofhand]

Last week I was preparing to take my pill before bed. I happened to be kinda drunk at the time, so I accidentally fumbled it and lost it down the sink drain. Oops. Not wanting to miss a day, I took the next day's pill instead. I was on week three of my pill pack, so I moved onto placebos one day earlier than I usually would.

Forward to this week - my period's started about the same time as it would have if I hadn't missed a day (in fact it actually came a day or two later than it usually would have... good ol' crazy body), but I'm looking at next week, when I'll be starting a new pack of pills.

My question is: should I start on the day that the placebos end (which means that I'd be starting a day earlier than I usually would - Sunday instead of Monday) or should I wait until I normally take the first pill of a new pack?

Thanks for your help!
