You buy a batch of 50 off the net and you still cut them in half to get more value for your dollar plus definately hide them from Husband so he knows your not a serial tester. Im definately one of those.
That is a great idea!! This is my first month using OPKs and I have used 19 out of the 20 that I bought. I think I can safely say I am....OBSESSED WITH POAS!!! Although reading they can sometimes work as a HPT didn't help matters.
