My Period is Abnormal?

Hi guys! So I was wondering if anyone else has this problem? The past few months my period has been late and not lasting as long. Usually with my birth control it lasts anywhere from 5-7 days and the past couple of times it's only lasted about one or 2 days? I'm supposed to get my period tomorrow but I don't feel any of the symptoms that I usually get. Can anyone help me out? 😭
