Do OPKs really expire after 30 days?

[Fizzyfefe]

The instructions for my OPKs say not to use after 30 days. Do they really expire that quickly, or is it just a way for the company to profit by persuading women to buy them more often? I have a whole bunch left over from last cycle and would hate to throw them out.

I bought a heap if cheapies online and they say expire April 2015.

They are all individually wrapped and sealed right?

No, the ones I have came in one sealed container. They are from CVS. They were expensive (around $17 for 20 strips), which is another reason I'd hate to throw them away.

That's probably the difference. Mine are all individually sealed and say not to open/ expose to air until your using them.
They were 50 for $11 in eBay.
It sounds like the ones you bought do that on purpose!

Amazon has them too. I think they are Wondfo. Its a mix of opk and hpt for about $20.

So that means they do expire, then? Or no?

Maybe I need to call the company, as I'm not really sure.

I would say yes they do, once exposed to air. Ones that are individually wrapped wouldn't
