If I take EllaOne 57 hours after intercourse, can I get pregnant? I did 2 pregnancy tests, both came out negative, but my period is already a week late, could it be due to taking a pill or am I pregnant?

Taking Ellaone may cause transient cycle disorders. Ellaone works within 120 hours of intercourse, so you have taken it correctly. If the pregnancy tests have also been done correctly, I see no reason to doubt the effectiveness of emergency contraception, but you can do one more test - just to be sure. Below you will find more information about pregnancy tests and the procedure to be performed: https://www.gdziepolek.pl/artykuly/test-ciazowy-jaki-wybrac-i-kiedy-zrobic
