Can taking birth control late by 6 hours for a week cause period to be late. My girlfriend and me were on vacation and for ten days she took her pill late between 3 to 5 hours each day?

Id also like to add that we had unprotected sex(ussually the pull out method) after a week of getting back from vacation (in the week after vacation she got back on the right schedule of taking it at the right time) and now we still havnt seen the period but have seen signs of it and its two weeks late now. can the Birth Control taking it like up to 5 hours late for those ten days casue her period to be screwed up?
