Missed a pill?

During my first month of taking the pill I took it religiously everyday at the right time. Then during my sugar pack I read you don't need to take them during those 7 days you can just skip. So I skipped them but I miscounted and I actually took an 8/9 day break instead of the 7 day set break you're supposed to have. Would that be considered a missed pill? Also how does it make it so you don't have to take a pill for a whole 7 days and still be protected? Please comment I'm confused!
