Trying to conceive? Chances are, you are already familiar with some of the procedures and devices used to help monitor things such as body temperature. So, we gather four of the best basal body thermometers on the market today to help you achieve your goal which is to get pregnant.

The Basics of Basal Body Thermometer

Those who have difficulties in conceiving need to diligently monitor their ovulation cycle to ensure the timing. One of the most important things to keep track is what we call basal temperature. It is not the usual thermometer available in the drugstores.

Moreover, this sensitive device can read even the smallest changes in the body’s temp over the course of a menstrual cycle. It is usually available in digital and glass thermometer. Others prefer the digital type as it reads more rapidly and more accurately compared to the mercury type.

It is ideal to take the basal temperature every morning, at the same time for the optimal result.

Basal Body Temperature (BBT)

During the “resting state” is when the body has its lowest temperature also known as its base or normal temp or BBT. The basal thermometer comes handy in determining the base temp after the resting period.

Ovulation signs are sometimes hard to notice. Take note that the base temp is the same every day but will have a significant rise during the woman’s ovulation period.

Using a basal thermometer will help you measure easier and more accurate under the conditions. Basically, women should track their BBT to know if they are ovulating. The basal temp can be taken through vaginal, rectal or oral. However, the vaginal temp is more precise.

The Proper Way of BBT Charting

On the average, a woman’s BBT ranges between 36.1°C (97°F) and 36.4°C before ovulation. But during ovulation, it rises up to 37°C.

Charting the BBT properly will help you notice a pattern and determine the changes that will happen during the cycle. Usually, women are keeping their record for at least three months to come up with the approximate ovulation day.

Here is how to do it:

  1. Take the first temperature upon waking up in the morning. Remember to take your temp every day at the same time.
  2. Any activity can possibly affect and make your temperature rise. Hence, do not get out of the bed until you have taken your BBT.
  3. It is also advisable not to eat, drink or walk to the bathroom after taking your BBT.
  4. Temperatures may vary so it is crucial to choose only one method and take the BBT the same way every day. You can either choose the oral, vaginal and rectal measurement.
  • Oral measurement is the most comfortable way. However, there are significant differences in the individual parts such as the front of the tongue or the back of it. Moreover, it requires longer time and more precision with the mouth closed.
  • Rectal measurement might be the least comfy method but it is considered the most stable in terms of results. One should maintain proper hygiene and disinfect the thermometer first before taking the BBT.
  • Vaginal measurement is the more accurate in terms of results. Also, you don’t need to disinfect the device and it doesn’t require any special treatment because of the vagina’s natural bacterial-killing micro-organisms. However, those who have fungal infections or other conditions affecting the vagina are not advisable to use this method.
