Plan B effect on period

Megan

So I took plan b about a month and a half ago now and before that my period came very regularly at the end of each month. After taking the plan b my period came about 2 and a half weeks early so I assumed that that was going to be the new date my cycle went around and reset my tracker accordingly. If that is my new date to get my period it makes me about 4 days late at this point and I’m starting to worry because typically my period was never late before taking the plan b. My question is whether the plan b could be further screwing with my cycle and if anyone’s had that happen or if maybe it means I’m pregnant because I am having sex regularly but always with a condom but I know mistakes happen. I know it’s only 4 days but I just thought I’d ask if anyone knew of any longer lasting cycle effects!
