How many days after missed period did you test positive?

I tested on my due date, it wasn't the strongest line but definitely positive

I tested on the 1st day of missed period (13dpo) and it was positive. Previously negative 10dpo.

I tested 2nd day of missed period. Had a very very faint line but could see it was positive. Next day did a clear blue digital test and result showed within about 30 seconds!

Tested positive 4 days before my period was due (about 11 days DPO).

I tested positive 2 days before but that's with a test 5 days before missed period test..x
