opk (daft) question

[spicyorange]

So Iv never done OPKs yet,, I see lots of people take pictures of them all lined up to compare each day but my packet says "do not read after 10 minutes" so I guess it must fade or get darker or something? I know pregnancy tests go a bit funny if you leave them too long, So how do you keep them and are they still accurate later?.

Anyone??

No they're not accurate after the time recommended.

They don't change much once dry, so sometimes ifs fun to keep them to identify a pattern.

But no, don't read them after the time limit
