Period

So last month I took a test and I’m not pregnant at all. And so today it was supposed to start but it’s just clear rn. Maybe it’s too early for my period this time. Or maybe it’s from needing my stomach meds for calming my stomach. Does anybody have any ideas to help.? So far it says I’m one day late but it just be another wack period. And I do have all of the symptoms for a period maybe it’s too early just yet.
