As soon as ovulation occurs in the female body, a large amount of the hormone progesterone is produced. It helps to increase body temperature within half a degree. Such an indicator can persist for two days. So ovulation divides the entire cycle into two phases. In the first, rectal temperature is lower than in the second, which lasts about two weeks.
If the basal temperature keeps the whole cycle at the same level, it is worth being examined for the ability to become pregnant, because this may be a sign of lack of ovulation. I think everyone knows how to measure rectal temperature. But why are we talking about a baseline at the same time? This is due to the fact that throughout the day the temperature indicator fluctuates. During the heat, it rises, and during the cold, respectively, decreases. It is affected by physical activity, the use of food, drinks, stressful situations.
Therefore, it will not be possible to choose a moment of rest during the day. A basal indicator is determined immediately after sleep, which should be at least 6 hours. It is better to do this through the anus, since this is how doctors determine the rectal temperature during pregnancy in the early stages. If you start doing this from the first day of your period, it will be best. The selected method should not change, since the values obtained by measuring in different places differ from each other.
Rectal temperature is measured for three minutes before you leave your bed immediately after waking up. You must also ensure that measurements are taken at the same time. This is due to the fact that indicators obtained more than half an hour earlier than a certain time or half an hour later are no longer taken into account. As for the measuring device, the thermometer can be either mercury or electronic. The main thing is that you use the same thermometer for one full cycle.
If rectal temperature is measured with a
mercury thermometer, it must be shaken several times before bedtime. Do not forget that you must necessarily write down the obtained indicators in a notebook or in a notebook. Do not rely on your memory, it can let you down. Various business trips, flights and transfers affect the reliability of temperature indicators. So if you have a need for these actions, measurements will have to be postponed until the next cycle.
Rectal temperature is not measured if you get sick with the illnesses that accompany fever. In this case, stop all measurements and recordings until you fully recover. All kinds of pharmaceuticals, such as sedatives, sleeping pills, hormones, etc., can also affect the accuracy of the thermometer. When you use any contraceptive, measuring basal temperature also makes no sense. As for the use of alcohol, you should refrain from this for the entire period of time when you are researching your own body.
