Positive and negative opks

I've been getting positive opks on Clearblue not the flashy smileys but solids... I have 3 testers and the all say positive but when I take the dye opks they come out negative. I've been getting positives for 3 days and I shouldn't ovulated until around the 14th. We've been dtd like usual just on case but I would like to have a day break to keep his numbers up so idk... it did it again tonight a positive clearblue but negative dye with the same urine sample. Anyone go through this?
