Birthcontrol question?

Ok so I accidentally didn't take some of the sugar pills because I was out late and I knew it would be ok. So last night I started my new pack which was Saturday. I didn't realize that I should have waited until Sunday!! I had one more extra fake pill to take. What should I do? Should I take Mondays pill today and jus be off one day? Won't that just equal out towards the end during the sugar pills? Idk what to do. I'm thinking just waitin until tomorrow to take Mondays on time. Will this mess up anything. If I do skip tonight how will this effect sex and how long before I'm completely protected again? I always use back up protection but I'm just curious. Thanks!!!
