Should I expect another period?🤔

Hello girls I've a question.

I had drunk sex the 2nd of February. Like two days after my period had ended. We used protection and all of that but since it was drunk sex I took my precautions and took Plan B. I had a period the week after I took Plan B. My period was not due till the first of March. My question is should I wait for another period? Or should I be worried in general? (I use two different apps to track my period.)
