$Tree OPK

[OnErth&InHvn]

I have the $Tree "Assured" brand, if that makes a difference? They are the purple cassette ones.

On the instructions it says the test line has to be the same color OR darker than control, but my question is: Does the WHOLE line have to be the same/darker or ANY part of the line?

From my experience, I would say the entire line. Seems odd that only part of the line would get darker because of the way the urine is wicked across the test lines. Perhaps try another and see if they're all doing that?

The positive OPKs I've gotten from dollar tree show the whole line darker than the control. Sometimes I get an almost positive the day before a positive.
