I broke my clear blue digital opk thing

Now I can't tell if I'm ovulating or not. Just got over a CP so idk when I'm ovulating. They're sending me new ones but I'll probably miss it by then. So these are my test from Monday , Tuesday and today. The first two were negative just a circle. Then I broke it and took the last anyway. So from your experience with Clear blue digitals is this positive or negative, the last one .
