Positive OPK then negative Clear blue? Help!

I'm so confused! I'm using the Target brand test sticks and I've been getting lines that have been getting darker slowly.

Today's test was positive, at least I think it is?

But then today I tried taking a Clear blue and it was negative?? I don't understand!

I think that was a positive because I took another tonight and it is clearly negative
