Thermometers

Ah, Dr Google answers ...

How the Basal Thermometer and Regular Thermometer Differ

There is a distinct difference between the basal thermometer and the regular thermometer. The basal thermometer measures basal body temperature by 10th’s of a degree whereas the regular thermometer measures your temperature by whole degrees only. It is important to note however that a digital thermometer will work for individuals desiring to measure their basal body temperature. The reason why you should use a basal thermometer to measure ovulation is that it is more exact and narrows down the temperature to a more precise number than a regular thermometer.

So I'll keep using my regular one (which shows to a 10th of a degree).

When I pluck up the guts

I don't think I agree with Dr Google. My understanding was that a BBT thermometer measuered to 2 decimal places, while a regular one measured to 1 d.p. I didn't know any thermometers measuered to whole degrees only - except maybe cooking ones!

I'm just using a normal one & it works fine. Not as accurate but plenty enough to see the shift, as said.

Yup normal digi worked for me.. i would keep using it and if you find you have flatish temps with out a big shift you might need a BBT as the extra decimal place may help ....

I'm sticking with the regular one for now. Two days in a row with 36.5 - we'll see what happens tomorrow.

I've ended up buying a BBT for $23 at the pharmacy. My normal one was taking up to 5 minutes to read and was plateauing on 36.5.
