What to consider when buying a basal thermometer?

When you are trying to conceive, you want to be at the top of your fertility game. That means knowing your body and its temperature changes. Basal body thermometers are one of the best ways to keep track of your body’s 24-hour temperature cycle, which follows the rise and fall of your basal body temperature (BBT).  BBT changes can indicate when ovulation is about to occur and help you predict your most fertile days. A basal body thermometer can help you determine when you are at the peak of your ovulation cycle, and help you pinpoint the date of your most fertile days.

Digital BBT thermometers are becoming incredibly popular these days, for a lot of good reasons. They are quick, easy to use, and have a simple interface that is usually just a screen. The cost of basal thermometers varies from a couple of dollars to over $100. The most expensive basal thermometers are usually more accurate, you can get away going for cheaper alternatives. Most thermometers only offer one type of measurement, like Fahrenheit, Celsius, or a combination of two.

Basal thermometers are a must-have device when trying to get pregnant as it will help you predict ovulation accurately by tracking your body temperature. Body temperature increases during ovulation time. By taking temperature measures every day after you wake up, you will track the period when you have higher chances of getting pregnant. The most important feature of a Basal Thermometer is its internal memory. You must pick a thermometer with plenty of memory to pick you a record of your previous reading. You should record your temperature first thing in the morning and store it in the internal memory to recall it when needed. This feature will help you have all your records on the device, eliminating the need to keep notes every day.

If you decide to go for an analog thermometer, you can’t avoid taking notes, so a digital thermometer is a great choice nowadays. You can opt for an analog thermometer, but digital ones are easy to operate, don’t need to reset every day, and you won’t have a fear of dropping in a shattering it to pieces.

Some basal thermometers have a large digital display, which makes them easier to read. However, you may find that a basal thermometer with a smaller digital display takes up less space on your nightstand. Another factor to consider when looking for a basal thermometer is its accuracy. Some basal thermometers are more accurate than others.

Accuracy is essential for the accuracy of basal thermometers. You might think this is obvious, but it’s amazing how many basal thermometers don’t deliver the kind of accuracy you need, especially when you’re trying to get pregnant. Basal thermometers are supposed to be used when your body temperature is at its lowest, which is in the early morning. It is also vital to take accurate readings, but nowadays, even the cheapest ones will be more than enough.  If you decide to go for a cheap thermometer, you may have to make some compromises as far as their features are concerned. Try to pick one that provides readings up to 1/100th degree Celsius or 0.09°F accuracy. Apart from their accuracy, the thermometers are also characterized by their measurement time, so again it is wise to get one that provides accurate and fast measurements. 

Spending a little more on a digital thermometer will get you 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. Check the screen size before buying, as some models come with tiny little screens that are difficult to read. The drawback of digital thermometers is that they are generally more expensive and require batteries, but they are a worthy investment. 

There are models in the market that can be synced with your mobile or tablet, syncing your daily measures to your device and access them with their application. If you decide to go for such a smart thermometer, make sure that your device is compatible; in most cases, the latest Android or Ios version is required, along with Bluetooth connectivity. Keep in mind that due to Bluetooth connection limitations, the device needs to be close to your mobile to sync, but in most cases, that will not be a problem.

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. Having a dedicated application on your mobile can provide you with the essential information and tracking, so this is something to consider regardless of the model you decide to buy. 

Things to check: 

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

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

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

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 keep track of any other conditions like lack of sleep or illness as those affect your temperature. Keep in mind that smoking also affects your basal temperature.

The “memory” feature on some basal thermometers is a convenient way to keep track of your temperature readings. This allows you to save your past readings, track your ovulation cycle, or compare this month’s temperature to last month’s. You just need to take your temperature every morning after getting out of bed. After several months, you’ll be able to see a pattern emerge. It’s usually recommended that you take your BBT for at least three months before you start trying to conceive, so you’ll be able to get the best idea of your body’s pattern.

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. Basically, it would help if you keep tracking your temperature daily to recognize the pattern that identifies your ovulation cycle. You’ll have to keep records of at least 3-4 months 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 at the same time each day for the best results. Having a digital basal thermometer will be handy to track this data into its internal memory.
