You can opt for an analog thermometer but we would recommend you get a digital one as they are easy to operate, don’t need to reset every day and you won’t have the fear of dropping in a shattering it to pieces. They are able to get an accurate reading and even the cheapest ones will be more than enough but you might have to make some compromises as far as their features are concerned. Spending a little more on a digital thermometer will get you and easier to read backlit screen that can be handy plus that memory recall functions that you will need to get rid of charting the old-fashioned way. If you decide to go for an analog one you should obviously check for some online service that would help you keep track or even a fertility application for your phone.

Why Take Basal Temperature?

This is the most accurate measurement of your temperature when there is no activity while sitting in bed as even a slight change in your position can lead to a slight temperature rise. It is important to also keep track of any other conditions like lack of sleep or illness as those affects your temperature also. Keep in mind that smoking also affects your basal temperature.

How to use it?

A woman’s temperature is around 97°F to 95°F regularly but after ovulation, it is rising between 97.5°F and 98.6°F. So basically you need to keep tracking your temperature daily in order to recognize the pattern that identifies your ovulation cycle. You’ll have to keep records of at least 3-4 months in order to have the necessary data to determine approximately the day of ovulation during your cycle. The best time to measure your temperature is when you wake up in the morning and preferably the same time each day for best results. This is where having a digital basal thermometer will be handy in order to track this data into its internal memory.

What to consider before buying a Basal Thermometer?

Beeping. Having a beeping function is handy so as to know when you have actually taken a temperature reading.

Backlight. It is wise to get a temperature with a backlit screen in order to be able to read the screen in a dark environment.

Internal Memory. It is important to get a model that would be able to keep track of your reading internal in order to avoid charting.
