OPK help picture

Hey everyone I've been using clearblue digital advanced ovulation test. I got a solid smile which was the peak two days ago. Then yesterday and today I just tested without the digital and they are darker then the day I got a solid smile which is the too test. Felt like I ovulated yesterday but if I'm still getting dark lines does it mean I might not of yet? 
Here's the picture....top is from Saturday am, then middle yesterday and bottom today at 12. Let me know!
