I only used a different thermometer twice, and that was to basically test the accuracy of the original one after using it, so I would temp twice back to back to make sure they were close to together, KWIM? I seem to be evening out the past few days, would stress make my temps go haywire?
I don't chart my CM because I have a really hard time figuring it out. Still working on that part.

?? To test vaginally, can I use the same thermometer? I *think* the instructions said I could. Do I just stick it up there? Sorry, TMI.
