Is it a digital thermometer? And does it record to the second decimal place? They are the best ones for the job.

I don't want to sound picky, but you said that you wake "around the same time each day usually". I'm afraid that in some cases, that just isn't good enough. I found it wasn't for me anyway and I know many other women on the FF message boards say the same. I found that setting the alarm for the same time each day was the ONLY way to get a truly accurate reading for the day.

Oh and after I switched to temping vaginally, it became a lot easier too because vaginal temps are more consistent as they aren't generally influenced by external factors such as mouth breathing and the temperature of the bedroom.
