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.
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...
