Has anyone used the clear blue advanced ovulation kit?

Today is my second day of using the opk and I got a blinky smiley face! Good thing we BDed in the early hours of the night. I am just in shock kinda because my period was last week. I may have been missing my ovulation days these past few months cause I didn't use opks
