Is my "other" bleeding the result of taking ellaOne?

Hi August 16 I had sexual intercourse (26th day of the cycle) we secured ourselves with condoms. We did not notice any crack or slippage, but for all certainty for the 4th day I took an ellaone tablet (I know that it was irresponsible on my part, and the tablet is intended for "crisis" situations) it was my 30th day of the cycle. My cycle lasts an average of 30-31 days. This time it was the same because two days later I got menstruation (the cycle lasted 31 days) but it was more stingy than usual, and it lasts longer because today it is the 7th day where it normally lasted about 5 days. 10 days after intercourse, I took a pregnancy test to be sure, it was negative. So is there still any chance of pregnancy? Is my "other" bleeding the result of taking a pill?
