I lost a pill.... what do I do?

Hi,

About 2 days ago I accidentally dropped one of my BC pills as I was about to take it and couldn't find it anywhere. I took the last pill in my pack (as the booklet instructed) to replace it and am still currently half way through my pack - so I havent missed any yet.

Now the booklet said that I will just start my period a day earlier. However, I had timed my packs purposely so that my period starts on a particular day - and I would like to keep that! Would any problems be caused if i just take 8 days of no pills instead of 7? So it would technically be like I missed my last pill instead of one in between.

Thanks
