I used mine in conjunction with temping and OPKs, which I would recommend until you are sure that it works for you. If I had gone on ttcing for awhile I probably would've just temped and used to MB, to save on OPKs (who am I kidding....I'm a POAS addict LOL! Thank goodness for lullaby conceptions).

I found it was best to use a fair bit of saliva, and then go and have a shower or something while waiting for it to dry. Like Sushee said, you really need to give it awhile, and make sure it is bone dry. Whe I was just getting the hang of it, I would do it two or three times each day, to be sure of the results. I found it most helpful in letting me know when to start OPKs, cos I O late and otherwise would have been starting them WAY too early! I used OPKs to help pin point my exact O date. It's worked twice now!

MB did work for me, but I could be confident of that because of the other methods I was using. It's now on loan to a friend, I really hope the babydust is rubbing off on her
