How many blinking faces will I get until I get a Peak day?

Hello. I was just wondering. I started the tests a few days ago the first 2 days I got blank faces. and the past 4 days including today i have got smiley faces they are blinking. Is there a different face that will show on my 2 peak days? I noticed it blinking. Does that make a difference. Is there a different face for your peak days than the other face? I noticed on the box there is one face with lines around it. that must mean blinking... so I am assuming on my peak day it will not blink. Am i right? Please help thanks.
