OPK help

Dana💄 • Mommy of 1 👶🏻
Ok so the package on my OPK said the darker the test line is the more likely you are to ovulate. If light it's a negative. But I took one yesterday and it was a clear no( top), I took another today and it's so much darker.  Maybe not enough to be positive 
 what do you guys think ? I am new to this ! 😔
