Thanks rufalina,
That was very informative. I have checked out the website and love it. I would like to purchase these OPK from the website. but our credit card has been hyjacked twice now and we are avoiding using it to purchase stuff online. Do you think the ones offered at the chemist are similar the Lullaby Conceptions ones?

Ohh can you believe my Maybe Baby saliva test gave me partial ferning this morning? Its CD2 and I am still bleeding. So I am very keen to try these OPK's. Thanks again for your help.
