Determine your ovulation with the basal body temperature

More and more women are dealing with their cycle and want to understand how their bodies work. And the trackle cycle computer should help with this: With trackle you easily determine your cycle, find out when your ovulation has taken place and know when you are fertile and when not. trackle is based on the symptothermal method. Two fertility indicators are included in the evaluation: your body core temperature and your Zervixschleim. trackle measures your temperature while you sleep and determines the lowest value: the basal body temperature. On this page you will learn more about what basal body temperature is and how it helps you to determine when you are ovulating. It's best to find out right away.

What is basal body temperature?

To clarify what basal body temperature is, let's first clarify why symptothermal method the temperature is measured at all. Shortly after ovulation, your body temperature regularly increases by around 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 increasingly released after ovulation. Among many other functions, it increases your body temperature in the second half of the cycle. If the rise in temperature has taken place, we know: you ovulated!

However, it is not enough to just measure the temperature once, because the temperature level alone does not tell us how high the progesterone is. So what we need is a temperature history.

In order to determine 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 when it is at rest – i.e. while you are sleeping. 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 cell makes its way towards the uterus and can now be fertilized. You can tell that you 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 around 0.2°C. However, it is not enough to measure the temperature only once, because the temperature level alone does not tell you how high the progesterone is. In order to determine an increase, you therefore need a temperature profile. With trackle you can easily measure your body core temperature and monitor your temperature development. trackle evaluates based on the rules of die symptothermal method from: 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

Observing your basal body temperature not only helps you to determine whether you have ovulated, but also whether you may be pregnant - this is particularly interesting for anyone who wants to have children. After ovulation, the temperature rises and stays at a higher level until the next menstrual period. If you don't have a period 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 gynecologist.

Why does the trackle cycle computer measure inside the body

While your body temperature always remains relatively constant inside your body so that your organs can work properly, the temperature on the skin's surface is subject to greater fluctuations. All the more so the further away the point at which the measurement is taken is from the trunk of the body. Anyone who tends to have cold feet or hands in winter will be familiar with this effect: when it’s cold, the extremities simply react much faster with less blood flow than the inside of the body. For the same reason, it is also recommended when taking a fever to do this in the ear, mouth or buttocks. Even under the armpit, the body temperature can sometimes be subject to significant fluctuations.

Measure basal body temperature: reliably with trackle

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

However, the actual basal body temperature can actually only be measured when you are completely at rest – that is, when you are sleeping!

and this is exactly what the trackle cycle computer does. Because the ingenious thing about our temperature sensor is that it automatically measures the actual basal body temperature while you sleep. This eliminates the need to measure at the same time every morning. The app also does the evaluation for you. trackle is simple, digital and safe and, as far as error susceptibility is concerned, prevails over the manually entered temperature curves.

Which external influences can influence the values?

Disruptive factors cause the basal body temperature to rise without ovulation having already taken place. Very important: Each of us is different and also reacts differently to stress & co. You can recognize a "disturbed" temperature reading by the fact that your temperature suddenly rises for a day or two and then falls again.

Common disruptive factors that affect basal body temperature in many women are:

- Drug consumption

– unusual consumption of alcohol

– short/disrupted night’s sleep

– Stress

– Time change

– Cold or illness

at trackle you have the possibility to exclude a disturbed temperature, it is not considered for the evaluation. But because we all react so differently to disruptive factors, the temperature does not necessarily have to rise - even if you are stressed or have a cold. It is therefore important that you do not cling immediately just because a party has taken place or you have a cold - but only when it affects your measured temperature.

Who is the method suitable for?

trackle and the symptothermal method work for everyone: women who are breastfeeding, women in shift work, women with irregular menstrual cycles, women who want to have children, women who want to get to know themselves and their bodies better and also women in all age groups.
