So confused

Okay so this is month 5 of trying and I'm using the Clearblue Digital ovulation predictor. My cycles are irregular. They keep getting longer the more periods I have. So these pictures are from Wednesday, Thursday, and today. I feel like today's is lighter but I've never gotten the positive smiley face so idk what's going on. Any thoughts?
