Hello

I am wondering if people are strong advocates for one or the other.

I am just beginning to chart my temps as well as CM, OPK's etc and have just found a brand new digital thermometer in my cupboard which claims to be accurate +/-0.1 between 35-39 degrees celsius and +/-0.2 under 35 or over 39 degrees celsius.

I am assuming this would only be any good for testing orally? What are peoples experiences of testing orally? I will buy a BBT if they are a safer bet of course

thanks for any input!
