Help with clearblue east o test?

[timsogirl]

Hi ladies!? I have a question...

On the non digital o test does the reference line have to be dark OR does ur just have to be as dark or lighter than the surge line to mean a positive surge?

Both of my lines are light with the surge line just a tad bit darker.

Thanks y'all!

As long as the test line is as dark or darker than the control line, then it's a pos.
