Morning after pill making period late

So I took the morning after pill nearly 2 weeks ago now and was the first time I had taken it. My periods haven’t Been very existent since coming off the depo injection a year and a half ago, but I did bleed a lot last month so think they were coming back to ‘normal’. But I was due on my period yesterday and normally if I don’t actually bleed I still get brown thick type of blood but I currently have nothing. So was just wondering if the morning after pill could be making my period later than it should be and wanted to know how late some peoples periods have been after taking planB. Just praying it is just the morning after pill delaying it😂
