I think you're ok, as long as you take your pill within 3 hours of your usual time, don't miss a night, and especially, use condoms if you do miss one.
I have a question, too.... I'm on ortho tri cyclen lo, and my boyfriend and I don't use condoms and he finishes inside me. I take my pill at the same time every night and haven't missed one, but has anyone gotten pregnant this way? Just curious.
