I've done that a few times were I forgot to take my pill almost 10 hours after my normal time... I've never had a problem with it effecting anything... but I've also been on my pill for awhile... I don't think you have anything to worry about...
Usually what the pill says is that you should take it as soon as you remember, but if you miss it multiple times in 1 pack, you should use another form of birth control. Sometimes women have odd symptoms during the pack if they have been off on taking the pill. I have had break through bleeding when I shouldn't have been menstruating and tender breasts.
