Inconsistency in New Choice ($) tests

[rawrrasaur]

Just to confirm that my surge is over, I bought a handful of opks from the dollar store and I opened the boxes and they were all different haha. So as an experiment I used the same urine on all of them and here are the results:

Just thought it might be interesting to you guys

Oh and btw, these were all done at the same time with the same urine and the pic was taken at 10 mins.

if you notice the control line is different shades, you always compare to the control line rather than other test and they all have varying amounts of dye in them.

they are not positive.
