👨‍👩‍👦‍👦 🍺 👨 Rules for measuring basal temperature to determine ovulation and pregnancy ✋🏼 ⛸️ 🍅

During the menstrual cycle, basal temperature is constantly changing. All these jumps occur under the influence of hormones, and temperature measurements can determine whether ovulation has occurred and whether conception has occurred. This temperature is an indicator of the phases of the menstrual cycle. A measurement of BT helps plan pregnancy. Each phase of the cycle has its own temperature indicators.

What is basal temperature?

The temperature, which is measured after sleep, is called basal, since you can not get out of bed. It is better to put the thermometer in front of you before going to bed. In frequent cases, it is measured for three months, this is necessary for some gynecological indications, to identify the first days of pregnancy, or you can use this information as a means of contraception. If you measure the basal temperature every day, you can determine the day of ovulation and plan your pregnancy, possibly even the sex of the child. If pregnancy is planned, then it is measured in the vagina, and in other cases it can be measured in the mouth.

Advantages and disadvantages of the measuring method

Determining ovulation by measuring basal temperature is one of the methods of pregnancy planning. The essence of this manipulation is to establish the most favorable moment for conceiving a child. Advantages of the method:

Simplicity and accessibility. Measurement of BT is carried out using a conventional mercury thermometer. Its presence is mandatory in any home.
Low cost in comparison with other methods of determining ovulation.
Safety and reliability.
Provided that it is correctly executed and has a regular cycle, BT helps to establish the slightest change in the state of the future mother.

Disadvantages of measuring BT:

The method is invalid. With any change in the hormonal background, BT indicators are considered invalid.
May not recognize ovulation period. This is due to special indicators of the individual norm in some women.
Requires long-term control. The measurement period of BT is 3-4 months.
May not show the presence of pregnancy, especially in the early stages.
The result is influenced by external factors: physical activity, alcohol and drug intake, stress.

Basal temperature before ovulation

Ovulation usually occurs on the day when the basal temperature rises quite sharply. Right now, a ripened egg leaves the follicle and expects fertilization by the fastest and tenacious sperm. As you know, the egg "lives" day, so it is very important not to miss the moment of ovulation for its successful fertilization.

The basal temperature in the first phase of the cycle is usually 36.3-36.5 ° C, but fluctuations may occur. Before the onset of ovulation, the temperature in the rectal zone rises sharply, on the day of its onset, the temperature is about 37.1-37.3 ° C. But still, these indicators can be different for different women and in different cases. The most important thing is the presence of a small gap in basal temperature, which indicates the onset of ovulation.

Basal temperature in ovulation

To determine the time of ovulation, you need to make a graph of basal body heat. Consider what it should be when the egg is ready for fertilization, and we will understand some of the features of its measurement. Conceive a child only in the middle of the menstrual period. This does not fit into the concept of one day.

In order to accurately determine the moment of ovulation, it is necessary to measure the basal temperature within 1-3 months, starting from the first day of the cycle under identical conditions for measuring temperature changes.
Perform manipulation upon waking up in the morning without getting out of bed. Preferably - at the same time.
The thermometer can be ordinary mercury or electronic. But a mercury thermometer shows more accurate numbers.
The most correct indicators will be achieved when determining the degree of heat in the anus. This can also be done in the vagina and in the oral cavity. It is important to choose one thing and not to change throughout the period.
To obtain the purest indicator, it is necessary to maintain a calm state of the body. Therefore, everything you need to take measurements should lie next to the bed in advance.

Ovulation. Temperature indicators

The measurements of basal temperature for determining ovulation are as follows:

Until the cell has matured, the temperature is in the range of 36.6 to 36.9 degrees.
During the release of the egg from the follicle, the indicators usually increase.
If the temperature did not rise above 37 degrees, then ovulation did not occur.

This condition is considered the norm and may be 2 or 3 times a year. But in fact, everything is quite individual. We cannot determine basal temperature strictly in degrees. It all depends on what the thermometer readings were earlier. Any deviations from previous indicators already indicate the beginning of ovulation. Normally, a temperature between 37-37.3 ° shows us that the moment of ovulation has arrived. In any case, it is more advisable to determine the day of egg maturation with the participation of a gynecologist.

Basal temperature after ovulation

Before ovulation, the temperature is slightly reduced and varies in the range of 36.2-36.5 degrees, and 2-3 days before the release of the egg, a drop phase occurs. After rupture of the follicle occurs, the temperature begins to rise slowly until it reaches a maximum of 37.1 °.

The second stage of the cycle after ovulation, on average, lasts from 2 to 16 days. In the absence of pregnancy, BT decreases by the time menstruation occurs, since the corpus luteum disappears, this leads to a decrease in progesterone, which causes menstruation. In the case of conception, BT does not fall and remains at a high level. The scatter in temperature for each woman will be individual due to different levels of hormones. Sometimes it is possible to establish pregnancy to a delay using measurements. On days 5-12, there is a pause for the time of implantation, during which the temperature decreases, and then rises and remains at the upper boundary. In some cases, during conception, the rectal temperature decreases, and the pregnancy is terminated, this usually happens even before the delay.

Scheduling

To measure basal temperature to determine pregnancy, you need to make a schedule.

Compilation Objectives:

Determination of the period of ovulation.
Predicting the day of the next menstruation.
Comparison of indicators of several cycles.
Determination of pregnancy.

The positive aspects of this method:

Availability.
Simplicity.
The possibility of holding at home.
High reliability.

The negative sides of the method:

It cannot be used as a method for predicting regular ovulation.
It cannot determine with 100% probability the time of the last ovulation.
Requires the use of additional methods of research cycle.

Temperature Measurement Technique

The following methods are available for measuring temperature:

Vaginal.
Anal.
Sublingual.

Important! You can not change the method of measuring temperature during a single cycle.

Temperature should be measured daily at the same time. This must be done immediately after sleep, in a horizontal position. You can measure the temperature with a conventional or digital thermometer. The latter gives more accurate readings. Measurement time - 1 minute with a digital thermometer and 5 minutes with an ordinary thermometer. Throughout the cycle, the type of thermometer does not change.

When maintaining graphical records, the thermometer should be recorded daily. Be sure to indicate the time of the manipulation. The presence of diseases, stressful situations, sleep disturbance, long trips, and drinking are indicated as additional information. The graph should include at least 5 indicators:

Date of.
Menstrual cycle day.
Temperature indicator.
The presence of vaginal discharge.
Additional Information.

The result of these observations will be the determination of a graph of temperature rise. The lowest temperature is observed on the eve of ovulation, high - after its passage. The same temperature during one cycle indicates the absence of ovulation.

Basal temperature during pregnancy

A woman after she realizes that she has become pregnant, learns a lot of interesting and new things about her daily rebuilding body. Together with the body, basal temperature indicators also change. They give the doctor the opportunity to judge the condition of the pregnant woman. Basal temperature is the rectal temperature of the body, which is measured in a calm state, without getting out of bed, after waking up. Even minimal physical activity can make BT indicators insignificant for detecting a pregnancy.

It is important that BT indicators fluctuate in each individual phase of the cycle. This is due to the preparation of the woman’s body to conceive a child and the support of optimal conditions for bearing it. A sign that the egg is developing correctly is that when measuring basal temperature during pregnancy, the indicators are at least 37 ° C. An increase in temperature in the middle of the menstrual cycle to more than thirty-seven degrees indicates the onset of ovulation. Regular increase in basal temperature over a long period of time can indicate pregnancy. A decrease in rectal temperature indicates the possible development of certain disorders in the body of a woman or in the fetus. An excessive increase in BT is a sign of an ectopic pregnancy. A temperature of more than thirty-eight degrees during the bearing of a child indicates the presence of an inflammatory process.
