New to OPK tests

Okay I know it's not positive so please don't tell me it's negative!! 
But does this line mean I am heading in the right direction of ovulation? 
I am new to testing, this was taken with afternoon urine and there is definitely a prominent line visible. I understand it needs to be as dark as the control line to be positive-  I just wondered if now I should keep on testing everyday seeing as though my periods are irregular and it is not clear when to test anyway.
