2-3 day before period ??

Ab

Got a 2-3 on clear blue today! My period is due tomorrow.. last period 1st - 6th jan.

got 1-2 on clear blue 5 days before my period was due. Clear positive on first response 6 days before.

Is this the norm result for one day before period ? My app is saying I’m 3 weeks 4 days.
