How to measure basal temperature
As already mentioned, the basal temperature will rise after ovulation, so before using it as a reference for fertile days, it will be necessary to take a daily temperature and record the value obtained for at least one month to know which ones. are the variations throughout the menstrual cycle. To do this, the following steps must be followed:
Use a digital thermometer. It is the most accurate. Do it every day and always at the same time, as body temperature varies throughout the day. It is best to do it every morning when you wake up. Always measure the temperature in the same place: mouth, anus, or vagina. It is not recommended to do it in the armpit because it can be more inaccurate.
If you have slept less than four hours. If you have drunk alcohol. If it has gone out at night. If you are sick. If you are stressed.
In this way, it will be verified that the temperature rises between 0.2 and 0.5 degrees the day after ovulation and will remain so until the moment of menstruation or after it. To know the fertile days, you will have to observe the cervical mucus, inserting the index finger into the vagina to obtain a sample. The mucus will appear egg white, with a clear color (almost transparent), a thick consistency, and, if you press lightly with your thumb when separated, fine threads are formed that do not break.
Measuring basal body temperature (BBT) and monitoring ovulation with a BBT chart can sometimes be tricky. Let’s take a quick look at how to get your basal body temperature (BBT) right and get pregnant faster.
What is basal body temperature?
Your basal body temperature (BBT) chart tells you if you’ve ovulated, not if you’re about to.
To plan sex, you need to record and track your basal body temperature (BBT) for at least one cycle, better two, or even three.
You will observe when you ovulated and will be able to plan your sexual relations in the days before the subsequent temperature increase.
How does the basal body temperature (BBT) chart change after ovulation?
When an egg is released, the body begins to produce progesterone, which raises body temperature.
Therefore, the basal body temperature (BBT) rises after ovulation. Keeping track of it is one way to check if you have ovulated.
If you take your basal body temperature (BBT) every day, you should see an increase of at least 0.4 ° C (0.72 ° F) the day after ovulation.
The method of using basal body temperature (BBT) to predict ovulation
Using basal body temperature (BBT) to predict ovulation is a more accessible alternative to having a gynecologic ultrasound. To do this, take your basal body temperature (BBT) daily for several cycles without interruption. Your basal body temperature tends to drop just before ovulation and rise sharply as soon as you ovulate.
In the first phase of the cycle, the basal body temperature (BBT) stays below 37 ° C (98.6 ° F). Most of the time, the basal body temperature (BBT) falls to values between 36.4 and 36.8 ° C (97.52-98.24 ° F) due to the low progesterone concentration. One day before ovulation, it is luteinizing hormone peaks, which may be accompanied by a further decrease in temperature of 0.2–0.3 ° C (0.36–0.54 ° F). After ovulation, the progesterone concentration rises sharply (multiplied by 10), causing a temperature jump above 37 ° C (98.6 ° F).
With the proper function of the corpus luteum, it will remain at this level for 10-14 days.
If the fertilized egg does not implant, the progesterone concentration and basal body temperature will drop before the period.
Why should you measure basal body temperature instead of average to track ovulation?
Recording your basal body temperature (BBT) is the easiest, cheapest, and most affordable way to detect ovulation.
Basal Body Temperature (BBT) is a base temperature customarily measured in the morning after you have slept (rested) at least 3-4 hours before any physical activity.
A body temperature that is not influenced by any external factor can be considered the most accurate.
What is the basal temperature?
Basal temperature is the temperature of the human body after five hours of sleep. In addition, measuring the basal temperature helps to know the woman’s fertile days to increase the chances of pregnancy.
Recording the basal body temperature daily is helpful to know whether the woman is in the ovulation phase, which is the process of the menstrual cycle in which an ovarian follicle ruptures and releases a mature egg so that it can be fertilized. (Ovulation problems are common causes of infertility.) It is a technique that requires perseverance and commitment on the woman since it can be uncomfortable and requires daily dedication, at least during a menstrual cycle. For this reason, it is discouraged to perform it routinely.
To make a basal temperature chart correctly, a woman should take her temperature for at least one month each morning at the same time, as soon as she wakes up and while in bed, and write it down on the corresponding data in a table.
After the release of the mature egg, the ovary begins to produce the hormone progesterone. In the middle of the menstrual cycle, the release of progesterone due to ovulation causes a rise in temperature ranging from 0.2 to 1 degrees Celsius. This indicates that ovulation has started.
However, this increase in temperature does not occur in all cases. This can happen to some women who ovulate regularly, meaning that they have menstrual cycles that last between 24 and 34 days from the beginning of one period to the beginning of the next. It can also happen that the basal temperature does not increase despite having started ovulation or that it is altered by factors unrelated to the reproductive cycle, such as alcohol or medication intake, fatigue, a cold, a copious dinner, and so on.
How to measure basal temperature
Specialists recommend measuring the temperature after having slept a minimum of five hours, always simultaneously and on an empty stomach, to increase reliability. Another recommendation is to choose a highly reliable glass or digital basal thermometer that allows the accuracy of up to one-tenth and not change it while monitoring is in progress.
The thermometer should be kept in the armpit for five minutes or until it gives the warning signal. It is essential not to move during this process because this could raise your body temperature slightly. When the result of the thermometer is between two marks, it is advisable to record the smaller number in the table.
At the end of the recording of a complete cycle, the usual thing would be to observe a point at which the temperature begins to be higher concerning the first days of the cycle. Basal temperature is a helpful indicator of fertility. After reviewing several cycles, the woman could observe a predictable pattern that would help him identify her fertile days.
