How to Use a Basal Thermometer

A natural method to conceive is the one using the basal thermometer, as this is a great method to determine the fertile period of a woman. The basal temperature must be measured along several menstrual cycles, to obtain as much information as possible about the particularities of the menstrual cycle.

The basal body thermometer is used to establish a pattern, and to create a model: growth-maxim-plateau-lowering. It was proven that since the moment of ovulation until the appearance of the menstrual bleeding, the temperature of the body grows compared with the previous phase of this phenomenon. The basal temperature grows with about 0.2-0.5 degrees, and the statistics shows that in the majority of cases (83%), the temperature grows suddenly, and in 15 % of cases, the temperature grows gradually, and in 2 %, the temperature remains constant, in which case establishing the fertile period with this kind of thermometer is impossible. This is why the basal body temperature chart is needed, and as a responsible woman, you will also need to find the chart that is suited for your body and for the changes that happen with your body.

How to use your basal thermometer effectively

Ovulation is a phenomenon that could last for minutes or hours, therefore we cannot talk about the beginning or the end of ovulation. You can determine when ovulation starts, but using a basal thermometer is not enough. The temperature of your body grows only during ovulation, but you are fertile two or three days before this phenomenon, therefore you must use the thermometer for a few months before you can predict your fertile days with accuracy.

For the first month, you will need to establish the normal basal temperature preceding ovulation. This must be considered

the basal body temperature (BBT), and you must consider this temperature as the normal temperature and as a base for your calculation. You will also have to establish when the temperature of the body starts to grow using the basal thermometer, and to write down the obtained values. For the second month, you will have to confirm the results with the basal body thermometer, and if the pattern is respected, it means that you have a normal and regulated ovulation. Therefore, for the third month, you can already predict this phenomenon using the basal body temperature thermometer. It is important to watch the charts from the previous months, and to establish the fertile period at two days before the day when the temperature of the body starts to grow.

What kinds of thermometers are available

The digital basal thermometer is the most accurate method to take your temperature, but this is the most expensive device of this kind, therefore you must be sure you can use it. Moreover, this thermometer usually comes with a predicting body temperature chart, and you should consult with your doctor to understand how to use the thermometer and how to use the chart.

Temperature first thing, then charting

Many women use the charts to “anticipate” the ovulation, and they are using the basal thermometer only to confirm the obtained results. This is wrong. The basal body thermometer is an accurate method to determine ovulation, but you will have to be patient, and to create the charts for at least two months, sometimes even three or four to determine a pattern. The results must also be confirmed using other methods such as the cervical mucus or the method of calendar.

When is a woman fertile

As said before, the basal body temperature thermometer is used to determine the ovulation, which is the maximum fertile period of a woman. In fact, the woman is fertile starting with two or three days before, as the spermatozoids can survive in the uterus for two or three days waiting for an ovule to fecundate. Any sexual contact can lead to pregnancy. The maximum of the basal temperature varies from woman to woman, being an individual characteristic that depends on many factors. It can be 36.9 or 37.4. There are also significant differences from one day to the other.

The characteristics of the BBT thermometer

The basal temperature ovulation is measured with a special thermometer, with an extended scale with temperatures from 36 to 38 degrees Celsius. A normal thermometer has a scale between 34 and 42 degrees Celsius, therefore the BBT is an accurate device, and this is why it is so expensive compared with the normal one. The newest models are able to create the basal thermometer chart, and with the help of a microcomputer, they will be able to anticipate the fertile period based on the observations you make for the first two or three months. The ovulation thermometer can be used orally, vaginally, or rectal, but it is recommended to take the temperature vaginally for higher precision, and it is also important to take the temperature the same way every time, meaning that you can’t take the temperature vaginally today and rectal tomorrow.
