Anyone using both FF and TCOYF charts to track bbt?

[TaurusBaby]

I have been using FF charts for the last 3 cycles but today I discovered the TCOYF charts and entered my details for this cycle. Just wondering if anyone else is using both of them at the same time and if so, do you find them to match? If they don't which one would you trust more?

Am at CD 20 today and FF tells me I O'd on CD16 but TCOYF says CD 18. Just curios...

I only use FF. That is weird. I have ever heard of that site before. I would trust FF though because that's the one that most people use.

Have you tried entering the other 2 cycles in as well? FF is probably different because it has more to go on with your past cycle information.

I've always used FF because I've found the TCOYF charts are quite odd. They seem to say you ovulate on your temp rise or a little bit after. Can you post a link to both of them? xx

Does TCOYF track other signs like FF? Perhaps TCOYF is "less advanced" than FF.
