I have the Target BBT pink thermometer and I think after this month we are parting ways. Last month I got confused by the temperature recall feature (my last temp blinks up on the screen for about a nanosecond and then 98.6 comes and stays up). So, I was stupidly thinking the 98.6 was my stored temperature and charting that.
My temps this month have been up and down, not really following much of a pattern, so I just took my temp twice in a row. 96.8 and 97.33. That's a big difference!
I just have a regular digital thermometer from WM - it's blue and white. I googled and googled and the only difference between bbts and regular thermometers seems to be that bbts go out 2 decimal places. Ya know, this whole process is neurotic enough that I'm fine with just tenths, thank you
And the recall feature on mine confused me too. Why would it save a number (97.7 on mine) that isn't the last temp? Makes no sense to me and screwed me up for about 2 weeks.
I used one from drugstore.com. It read to two decimal places, but honestly I think that's excessive and usually just rounded it to nearest tenth of a degree. More decimal places doesn't make it more accurate or more precise....
Tarheels, that's funny because I read that BBT thermometers read to the tenth of a degree, whereas non-BBT usually only read to the .2 (so if you got 97.3, it would either read 97.2 or 97.4, which isn't good enough to identify a half degree temp increase). I found a thermometer reading to the hundredths to be really annoying, especially when two temperatures taken one minute apart could be as much as .25 off....
Oh yeah, v, you're right - that was another supposed difference - that regular digitals count by .2. But my WM cheapie counts all the numbers. I really think bbts are a marketing ploy now - I'm sure they were needed X years ago, but now that the technology's so cheap, the features are available on regular thermometers.
