Ok - I am not a specialist, but I will try :

Where is the best place to find a chart? try googling fertility friend - alternatively, Alan made a spreadsheet a while ago, I have it on my home pc and i will send it to you

When do I start charting? as soon as you like - even just to get into the rhythym of doing it

What do I record? (i.e. temp, CM etc) temp - cm - and cervical position

How do I know when I am ovulating? Your temp will dip slighlty - i suggest you do some googling on this very important part - but if you get fertility friend it will give you a graph and will show you when you are fertile

Do I have to temp? yep! before you gt out of bed each morning.

There is a clinic where I live that teaches the Billing Method. Has anyone been to one of these seminars? Is it worth DH and I going? sounds good to me!
