In my opinion - there is no need - the EllOne tablet is only effective if you take it within 120 hours of intercourse. Adopting it "in advance" will not be effective. I think you would distinguish diarrhoea from simple diarrhoea. Passing loose stool after taking the tablet does not affect its effectiveness. Only if diarrhoea occurred - that is, a minimum of 3 watery stools within 3-4 hours of taking the tablet, protection could be reduced. If anything still bothers you, you can do a home pregnancy test, which you will buy at the pharmacy. The test detects already very early pregnancy (10-12 days). Here you can compare the prices of sample tests and order the test with home delivery or collection at the pharmacy: https://www.gdziepolek.pl/produkty/97388/domowe-laboratorium-pink-test-ciazowy-strumieniowy-super-czuly-test/apteki https://www.gdziepolek.pl/produkty/91349/domowe-laboratorium-pink-test-ciazowy-plytkowy-super-czuly-test/apteki

However, if it turns out that one of the active tablets did not take (assuming that diarrhea could have occurred in the cycle, which I mistook for ordinary diarrhoea), should I take the ellaone tablet to be sure? Maybe the question is stupid, but I've only been using hormonal contraception for a few months and I'm still stressed out
