Basal body temperature

I bought a 99p one from the 99p store. Kids one. Works fine. )tested on hubby! against a mercury one. Easier to read too.

Hi - I believe Mercury ones have been banned in EU on safety grounds as Mercury is extremely poisonous both for individual and environment. You can, however, still buy liquid thermometers - red liquid - but mixed reviews. I use a digital one. End of the day it is not the exact number that matters, as we all have a personal set-point and natural variation through time and day anyway. I would watch relative temperature increase or decrease.

Hey I do this with a digital thermometer. Bought a cheap one and it seemed to give me really low readings: 34.9 etc so bought a infrared ear thermometer and my readings have been higher but vary between 35.4-36.4 now. I feel its more reliable than the other one.

I used two different cheap digital thermometers, Both seemed to work ok.

I have taken my basal temperature almost all of my thyroid life with a digital thermometer and learnt a few things along the way! I also had a Mercury thermometer in those early days so I was able to compare. Following the instructions for the digital was useless! So I started ignoring the correct temperature was when it bleeped but left it until the thermometer switched off and that gave me an accurate reading. One day my Mercury thermometer disappeared! I couldn't thing of a reason the Borrowers may have had for it so could only conclude that the cleaners had dropped it so nothing to check with anymore so then I always tended to have more that one digital and always checked that the new one to the fold was same as the others. This last few weeks have been taking Tramadol following a nasty fall and my temperature has increased! But have found a comment that that this is a side affect so hoping that this increase will drop back when my life is back to normal!
