Hi - can anyone tell me if the ebay OPKs they used worked? I have obvious EWCM at the moment, but no positive on the OPK. I also have a lot of spotting with it too, which is worrying me. We have been trying for two years for #3 and no luck at all. Been for tests and everything should be ok, but I am not convinced.... should I be relying on these OPk's?
