answer brand opk positive?

Stephanie
Is this a positive? This is my first month using this brand and they are so hard to read! I really think this is a positive and these strips just aren't the best in being confident about it lol. What do you think?? 
UPDATE :
today on cd21 I got a darker positive so I think this may be it. With the other strip above I never ended up getting the ovulation pain like I normally do so I kept testing to see. But I worry that this ovulation is too late... every other time I've had large eggs and good lining but ovulated late I didn't get a BFP :/ but then again those are the only type of cycles I've really had other than 1 cycle with good follicle but bad lining. 
Here is the test strip today:
