I've been using FertilityFriend.com to chart - but only by listing my menses, symptoms, etc. Anyway, I've decided to step it up a notch and wondered what the best method is - should I just buy a BBT and start temping or is it better to use the Ovulation tests?? TIA!

its actually best to do both

Personally for me it was just temping...I never got the tests to work for me and never ever got a positive line.

Temping will give you the most info. It will tell you if you O'd and when you O'd. OPK's are meant to be an added item and they will tell you when you are having an LH surge but that does not guarentee that you actually O'd. I just finished the charting course over at fertility friend and learned a lot from it
