Fertility Monitors ~v~ OPK's?

[greenlizard]

Hi, I would interested in hearing anyone's experience in using the Clear Blue Fertility Monitor and if you thought it gave you anything over an above using an OPK and/or charting?

I am considering buying one but not sure of the difference? Are they worth it - or just one more thing to get confused/stressed/obsessed with!

I asked a similar question a few months ago and the answer I got seemed to be that if you get results from using OPKs (as I do), then there is no need to use the CBFM as it measures the same hormone. However if I remember correctly only one person responded so would be interested in hearing other people's thoughts!
