Preconception.com.au, Fertility Friend and Soundtells

Are all driving me mad in one way or another.
Preconception.com.au is showing basically my whole cycle to be fertile days.
Fertility Friend - i cant find how to change my cycle length, and its giving me dates that i know are off
and Soundtells doenst allow you to enter details of CM and BBT, it just relys on its own calculations for fertile days.
So, has anyone found a good on line resource that is easy to use? Basically, while we are not TTC i am entering details on line and when DP gets up in the morning he checks to see if we need to be careful - i HATE him asking me if we need to use protection just when we are about to make love! And i want him to be responsible too - if we had a whoopsie IYKWIM?
Any suggestions?

If you can find Alan, i remember a little while ago he had a thread about charting in Excel. He should be able to point you in the right direction. If you need help with FF just pm me and i can help you change your cycle length - maybe just not this week - having a really bad one
