Determine your ovulation with the basal body temperature

More and more women are concerned with their cycle and want to understand how their body works. And the trackle cycle computer is designed to help: With trackle you can easily determine your cycle, find out when you ovulate and know when you are fertile and when you are not. trackle is based on the symptothermal method. Two fertility indicators are included in the evaluation: Your core body temperature and your cervical mucus. trackle measures your temperature while you sleep and determines the lowest value: the basal body temperature. On this page you can find out more about what basal body temperature is and how it helps you to determine your ovulation. Find out more right now.

What is the basal body temperature?

In order to clarify what basal body temperature is, let's first clarify the question of why the symptothermal method takes your temperature in the first place. Shortly after ovulation, your body temperature regularly rises by about 0.2 degrees compared to the first half of the cycle. The fact that this works so reliably is due to the hormone progesterone, which is released more strongly after ovulation. Among many other functions, it causes your body temperature to rise in the second half of the cycle. When the temperature has risen, we know: You have ovulated!

But it's not enough to just take your temperature once, because the temperature alone doesn't tell us how high the progesterone is. So what we need is a temperature history.

To establish an undisturbed temperature course, you need the temperature at rest: and that is the basal body temperature. It is the lowest core body temperature that your body reaches at rest, i.e. while you are asleep. It is usually measured in the second half of the night, i.e. in the very early hours of the morning.

Basal Body Temperature & Ovulation

Ovulation is the moment when the mature egg makes its way towards the uterus and can now be fertilised. You can tell that you have ovulated by looking at your core body temperature. After you ovulate, a hormone is released: progesterone. This causes your core body temperature to rise – by approximately 0.2°C. However, it is not enough to take your temperature only once, because the temperature alone does not tell you how high the progesterone is. To detect an increase, you need a temperature curve. With trackle you can easily measure your core body temperature and observe your temperature curve. trackle evaluates on the basis of 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. This double check makes the method so safe!

Basal Body Temperature & Pregnancy

Monitoring your basal body temperature not only helps you to find out whether you have ovulated, but also whether you might be pregnant – this is particularly interesting for anyone who wants to have a baby. After ovulation, the temperature rises and remains at a higher level until the next menstruation. If your menstruation does not occur and your basal body temperature has remained at a higher level for at least 18 days, it may be time for a pregnancy test or a visit to your gynaecologist.

Why does the trackle cycle computer measure inside the body?

While your body temperature inside the body always remains relatively constant so that your organs can work properly, the temperature on the surface of the skin is subject to greater fluctuations. The further away from the trunk of the body the spot where the temperature is measured, the more so. If you tend to have cold feet or hands in winter, you will be familiar with this effect: The extremities simply react much more quickly in the cold with less blood flow than the inside of the body. For the same reason, when taking a temperature, it is recommended to do so in the ear, mouth or buttocks. Even under the armpit, the body temperature can sometimes be subject to considerable fluctuations.

Measuring basal body temperature: reliably with trackle

One temperature that is very close to the basal body temperature is the waking temperature. This is the temperature that you measure directly after waking up – and always at the same time for three minutes. In the past, there was no way to measure the actual basal body temperature, so the wake-up temperature was taken. However, this is often not so easy to implement for women who, for example, work shifts or have small children.

The actual basal body temperature can only be measured when you are completely at rest – that is, when you are asleep!

And that's exactly what the trackle cycle computer does. The ingenious thing about our temperature sensor is that it automatically measures the actual basal body temperature while you are asleep. This means you don't have to measure it every morning at the same time. And the app also takes care of the analysis for you. trackle is simple, digital and secure, and thus stands up to the manually entered temperature curves in terms of susceptibility to errors.

What external influences can affect the values?

Disturbing factors cause the basal body temperature to rise without ovulation having already taken place. Very important: Each of us is different and reacts differently to stress & co. You can recognise a “disturbed" temperature value by the fact that your temperature suddenly rises for one or two days and then drops again.

Common factors that influence the basal body temperature of many women are:

– drug use

– Unaccustomed alcohol consumption

– Short/disturbed sleep

– stress

– time change

– cold or illness

With trackle you have the possibility to exclude a disturbed temperature, it will not be taken into account for the evaluation. However, because we all react so differently to disturbing factors, the temperature does not necessarily have to go up – even if you are stressed or have a cold. Therefore, it is important that you do not clamp immediately just because a party has taken place or you have a cold – but only when it affects your measured temperature.
