Using basal temperature to determine your ovulation

More and more women are interested in their cycle and want to understand how their body works. And the trackle cycle computer is there to help them: With trackle, you can easily determine your cycle, know when you ovulated and when you are fertile or not. trackle is based on the symptothermal method. Two fertility indicators are taken into account in the assessment: Your core body temperature and your cervical mucus. trackle measures your temperature while you sleep and determines the lowest value: the basal temperature. On this page, you will learn more about what basal body temperature is and how it helps you determine your ovulation. Get informed now.

What is basal temperature?

In order to clarify what basal temperature is, we will first ask why temperature is measured as part of the sympto-thermal method. Shortly after ovulation, your body temperature steadily increases about 0.2 degrees from the first half of cycle. If it works so reliably, it is thanks to the hormone progesterone, which is secreted in an increased way after ovulation. Among its many functions, it raises your body temperature during the second half of the cycle. If this temperature rise has taken place, we know it: You have ovulated !

But taking the temperature just once is not enough, because the temperature level alone does not tell us what the progesterone level is. So what we need is a temperature curve.

To establish an undisturbed temperature curve, you need the temperature at rest: and this is the basal temperature. It is the lowest core body temperature that your body reaches at rest, that is, while you sleep. Most of the time, it is measured in the second part of the night, that is to say very early in the morning.

Basal temperature & ovulation

L'ovulation is when the mature egg makes its way to the uterus and can be fertilized. You can tell that you have ovulated by looking at your internal body temperature. After you ovulate, a hormone is secreted: progesterone. This has the effect of raising your core body temperature - by about 0.2°C. But taking your temperature just once isn't enough, because the temperature level alone doesn't tell you what the progesterone level is. To see an increase, you need a temperature curve. With trackle you can easily measure your core body temperature and observe your temperature development. trackle evaluates the data based on the rules of the symptothermal method: This means that in addition to your core body temperature, the consistency of your cervical mucus is also evaluated. It is this double control that makes the method so safe!

Basal temperature & pregnancy

Observing your basal temperature not only helps you to determine whether you have ovulated, but also whether a pregnancy is possibly underway - which is particularly interesting for those who wish to have a child. After ovulation, the temperature rises and remains at a high level until the next period. If you don't get your period and your basal temperature has been high for at least 18 days, it might be time to take a pregnancy test or see your gynecologist.

  • It is best to measure the basal body temperature inside the body, because: While your body temperature inside the body always remains relatively constant so that your organs can work properly, the temperature on the skin surface is subject to greater fluctuations. The further away from the body core the spot where the temperature is measured, the greater the fluctuations. If you tend to have cold feet or hands in winter, you will be familiar with this effect: The extremities react much faster to cold with lower blood flow than the inside of the body. For the same reason, it is also recommended when taking a temperature that this is best done in the ear, mouth or buttocks. Even under the armpit, the body temperature can sometimes be subject to considerable fluctuations. It is therefore not easy to take meaningful basal body temperature readings, unless you measure inside the body, as the trackle fertility monitor does.

Basal temperature measurement: reliable with trackle

A temperature that comes very close to the basal temperature is the temperature on waking. This is the temperature that is measured immediately after waking up - always at the same time and for three minutes. In the past, it was not possible to measure the actual basal temperature, which is why the temperature was taken when waking up. But this is often not easy to implement for women who, for example, work in shifts or who have young children.

But the actual basal temperature can only be measured at complete rest - that is, when you are sleeping!

And that's exactly what the computer does cycle trackle. Because the genius of our temperature sensor is that it automatically measures the actual basal temperature while you sleep. It is therefore no longer necessary to measure it every morning at the same time. And the app also takes care of the assessment for you. trackle is simple, digital and safe and thus stands out in terms of the risk of error with respect to manually entered temperature curves.

  • Disturbing factors cause an increase in basal temperature without ovulation having already occurred. Very important: each of us is different and reacts differently to stress and the like. You can recognize a "disturbed" temperature value by the fact that your temperature suddenly rises for one or two days and then drops again.

  • Frequent disturbing factors that influence the basal temperature in many women are:

    - drug use
    - unusual alcohol consumption
    - a short/disturbed night's rest
    - stress
    - Time change
    - cold or illness

Who is this method for?

trackle and method sympto-thermal work for everyone: women who are breastfeeding, women who work in shifts, women who have irregular cycles, women who want to have a child, women who want to know themselves and their bodies better and also women of all ages.
