ClearBlue O PK

Ok so I think I messed up lol. I bought a new clearblue digital opk and used the new digital reader and got a O low fertility. This confused me because I have got a blinky ☺ high fertility sun mon Tue and today but no peak. After reading the instructions and doing some Google research I think the tester has a memory of some sort and that I should have used my old tester with a new stick. I tried this with another bed test stick an sure enough I got a blinky ☺. Do you ladies still think I am in the high fertility window?
