I’m Charting My Body Temperature. Should I Use a Glass or Digital Thermometer?

When you are trying to conceive you question everything, including what type of thermometer to use when you are charting your temperature. You may choose either a glass or digital basal thermometer and there are positives and negatives to each.

For example, glass basal thermometers will provide you with accurate readings, however they are quite difficult to read. This is annoying and can make it difficult to record the accurate temperature. Another drawback to glass thermometers is that they can break and they are so fragile that it’s not difficult to break them by accident.

On the other hand, digital thermometers will allow you to take your basal body temperature and they won’t break! Another plus is that they beep once your temperature has been taken. That way you know you have an accurate temperature and you don’t have to keep track of time or anything. Most digital basal thermometers also have a “memory” where they store your last temperature reading. That way, if you forgot to record it or entered it incorrectly you can double check it on the thermometer. Digital thermometers travel well, too, because you can just toss it in a bag and not worry about it getting broken. Because of this digital thermometers are probably your best bet.


Use a Basal Thermometer

It must be said that if you want to chart your basal body temperature you must use a basal thermometer. They aren’t the same as your regular old thermometer and can detect even small changes in hormones in the female body. That’s because the thermometer takes the temperature out to the 100th degree rather than just the 10th. That means you are able to better detect any subtle hormonal changes. It is likely that with a regular digital thermometer you won’t notice any temperature changes at all.
