Cheap OPKs fade alot after a week?

[ballbaby]

Last week I had some very close +'s and one fairly certain +, took pictures to ensure in not losing my mind but now the test lines have ALL faded! The positive one and near pos ones are darker faded but none equal line anymore.

Is this normal with cheapie opks?

I even noticed the fade occuring after the ten minute mark!

I find that they fade too.
For a few cycles, I obsessively kept all my OPK 'to compare' with future cycles, but after a while it became very apparent that they faded so much it made keeping them pointless.

I can get a positive in the afternoon and by evening it will be a lot fainter.
