Does twice putting stool affect the effectiveness of contraception?

Hello, biore contraceptive pills axia conti. I took the tablet at a permanent time and immediately went to give the stool rather normal. Two hours later I dismiss another already rather rare. Is it possible that the tablet has not been ed and expelled? How is the chance to get in this case? I would add that I do not have a spare package, so I can not take another. I heard about taking the next one from the current packaging and scraping the cycle sle do not know how it works
