Julesy - I was referring to drinking water (or anything much) prior to testing with OPK's. Apparently you should restrict drinking for 2 hours before testing as the LH surge may not be detected if urine sample is diluted.

BTW - If you think that's a dumb question you should see some of mine!!!

Isn't the ferning frustrating!! I am going to try temping next month and try different OPK's as I've had no luck with these (from ebay). They work well for some but not for me.
