Question about ortho-tricyclen birth control pills.?

I dont usually have any concerns about my birth control, because I always take them correctly. But last Friday, when I was taking my pill before bed, I saw I was taking Thursdays pill. I looked closer in my pack and saw that a week and a half ago, I had mistakenly took a green sugar pill, instead of my white one. I usually take them in my room at night while it is dark, so that is why it took me so long to notice. Anyways, on Friday I went ahead and took Thursday and Fridays pill. And I had been taking white ones every day since that one day. Do you think I need to be concerned about anything. Or no?
