Hi Bindy
I did pay up and become a member of FF for the purposes of charting, I loved it and thought it was a great tool. (Although I think I became a little obsessed with it...LOL).

Although we ended up having to go IVF/ICSI to conceive, the charts did show and confirm to me that my cycles were Ok and our timing was also good in relation to ovulating etc.

It proved that we had issues else where and so started having other tests to try and work out why we were not conceiving.

I agree with Monnie I probably wouldn't use it for 'info' as theres so many sights that offer that for free.
