Taking into account that you took birth control pills correctly (a one-time delay of 5 hours does not affect the effectiveness of contraception), and additionally the intercourse was intermittent, the probability of pregnancy is negligible. Usually, withdrawal bleeding occurs within 2-3 days of taking the last active tablet, but this is not a rule and sometimes without a specific reason bleeding may be delayed or not occur at all. If withdrawal bleeding does not occur even after finishing taking the tablets from the next package, a pregnancy test should be performed to rule out a possible pregnancy, e.g.: https://www.gdziepolek.pl/produkty/97388/domowe-laboratorium-pink-test-ciazowy-strumieniowy-super-czuly-test/apteki I enclose additional materials that may be helpful: https://www.gdziepolek.pl/artykuly/jak-prawidlowo-stosowac-antykoncepcje https://www.gdziepolek.pl/artykuly/jakie-leki-oslabiaja-skutecznosc-antykoncepcji https://www.gdziepolek.pl/produkty/84769/yaz-tabletki-powlekane/ulotka
