Shortened placebo or missed pill?

Hello!

My problem is following... I've been taking my 21-days pack consistently (till 25th). Then on 26th which was supposed to be my first day of placebo week I didn't take it because I simply forgot (my intention was to start a new pack without 7-days pause). As soon as I remembered on 27th (exactly 24 hours later), I took two of them as if it were "missed pill" (stupid, stupid me). Because I could have taken a break for two more days and then start a new pack, as if I would shorten 7-days pause to 3-days pause which is even recommendable to do once in a while? 

I'm confused now, because I don't know if I should treat this one pill as missed (therefore 7 days of additional protection is needed) or as placebo day (no additional protection is needed). 

Thank you in advance for all your advices, ideas, knowledge... :)
