Temperature in the first days of pregnancy. Can fever be a sign of pregnancy? The first signs of pregnancy in the early stages

When a woman learns about her new position, she begins to experience new sensations. They are not always pleasant. It can be weakness, drowsiness, malaise, aching pain in the groin area, nasal congestion, hot or cold flashes, and so on. One of the most alarming sensations is elevated body temperature. In this article, we will look at whether a high temperature in the early days of pregnancy is normal or if you should beware.

first days of pregnancy

Change in body temperature

A woman's body temperature fluctuates much more frequently than a man's body temperature. This is due to the fact that a woman's body undergoes changes every month. For example, the temperature balance may change depending on the phasemenstrual cycle. Accordingly, an increase in temperature in the first days of pregnancy is also normal for the female body.

As you know, the menstrual cycle includes several phases. During each of the phases, certain processes occur: the maturation of the egg, its release into the abdominal cavity, fertilization and further development, or death and removal from the body if fertilization has not occurred.

The appropriate conditions are necessary for each of the processes. For example, if fertilization has occurred, then a higher temperature is required to maintain the vital activity of the egg than for the period of its maturation. Therefore, with the onset of ovulation, body temperature rises and remains until the end of the menstrual cycle in case of fertilization. In the first days of pregnancy, the temperature remains elevated, which helps the fetus to gain a foothold in the uterus and begin its development.

Progesterone hormone

toxicosis of pregnancy

The temperature in the first days of pregnancy is influenced by the hormone progesterone. With the onset of ovulation, and then conception, it begins to be produced in large quantities, which prevents the body from expelling heat. This process can be observed throughout the first trimester, since the corpus luteum lives during this period, which produces this hormone. There are situations when the temperature remains elevated throughout pregnancy, but you should not take this for a pathology. This factor does not in any way affect the development of the child.

Could the temperature besign of pregnancy? Undoubtedly. It is even recommended to measure it every day to understand if a miscarriage has occurred, especially if spotting is observed.

Weakened immunity and intoxication

Another reason for fever as the first sign of early pregnancy is a woman's reduced immunity. This is an absolutely normal phenomenon provided by nature. This is necessary so that the mother's body does not fight with the "foreign" body and allows the embryo to easily attach in the uterus. For the same reason, nausea occurs. Fever and nausea in the first days of pregnancy make it clear that fertilization has occurred and a new life has arisen in the female body.

Immunity is reduced temporarily. As soon as the embryo is fixed in the uterus and begins to develop, when it has its own immune system, then the woman's immunity will become the same.

Some believe that the change in thermoregulation is due to intoxication in the body of a woman caused by the development of the embryo. It is for this reason that there is an opinion that in vegetarians who do not eat meat, such reactions of the body are less common.

What can you see on a thermometer?

temperature during pregnancy

So, what temperature in the first days of pregnancy is considered normal? The generally accepted average is 36.6. But this figure can fluctuate by several tenths.

Heightened temperature is already considered to be from 37 оС and above. If a woman before conception had an increasedtemperature, then after fertilization it will be an order of magnitude higher. You should not be afraid of this. In the early days of pregnancy, a temperature of 37 degrees or higher is normal. The process of embryo implantation is very complicated, so changing the body's thermoregulation is the most common safe thing.

Basal body temperature

To monitor women's he alth, basal temperature is also measured. This is the internal temperature, which is measured in the anus immediately after waking up for 5-7 minutes.

What is the basal temperature on the first day of pregnancy? During menstruation, the basal temperature is 36.7-36.9 degrees. At the time of ovulation, it rises, its rate is 37.2-37.4 degrees. If conception did not occur, then 5-8 days before the date of the expected menstruation, it begins to decline. However, if the egg has been fertilized, then the basal body temperature usually does not change.

Measurement of basal temperature is one of the most popular and reliable methods for determining the presence of pregnancy. Women who constantly monitor their core temperature can tell they are pregnant even before they miss their period.

What can affect basal body temperature?


There are many factors that can change your true basal temperature reading. Among them:

  • sleep less than 4-6 hours;
  • sexual intercourse (must be at least 4 hours);
  • uncomfortable ambient temperature(too hot or too cold);
  • measuring temperature at different times (recommended to measure in the morning at the same time after waking up);
  • the presence of acute inflammatory diseases or chronic in the acute stage;
  • taking alcohol or psychotropic drugs the night before.

In order to identify the temperature characteristics of your body, you need to measure the basal temperature for three or more menstrual cycles. Thus, you can get a more complete picture of the hormonal background of a woman.

Temperature drop

The increase in temperature does not always go unnoticed. Some women feel unwell, others do not experience any new sensations.

Against the background of pregnancy, the temperature can not only rise, but also fall. This may indicate insufficient production of progesterone, which is necessary to maintain pregnancy. Of course, this can only be a feature of your body, but it is still necessary to inform the doctor about this. It is likely that hormone therapy will be needed to maintain the pregnancy. A particularly important indicator is the sharp drop in temperature after it has risen.

Causes of low temperatures

weakness and fever

Reduced temperatures during pregnancy can be observed with the following concomitant conditions of a woman:

  • individual characteristics of the female body;
  • intoxication of the body (toxicosis);
  • overwork;
  • iron deficiency anemia;
  • malnutrition and lack of nutrients in the body;
  • disturbances in the endocrine system.

Reducing the temperature can bring as many unpleasant symptoms as an increase. A woman may feel a general weakness of the body, increased sweating, headaches, dizziness, up to loss of consciousness.

Thermoregulation in a woman with the onset of pregnancy is a very individual indicator. A low or high body temperature in the absence of other unpleasant symptoms is not a pathological sign. But for more reliable information about the development of your baby, you should consult a doctor.

How to prevent temperature fluctuations?

To avoid temperature fluctuations at the beginning of pregnancy, it is customary to follow certain measures. They are no different from the prevention of colds and viral diseases.

  1. It is necessary to ventilate the rooms in the house more often, especially those where the expectant mother is most often. However, the rooms cannot be cooled down. Therefore, it is important not only to ventilate, but also to heat the rooms well.
  2. It is better not to visit crowded places, especially if various epidemics are observed during this period (SARS, influenza, tuberculosis, etc.). If a visit cannot be avoided, then a mask and other personal protective equipment must be used.
  3. He alth measures must be observed: do not get cold, wash hands after the street, clean the nasal passages and oral cavity andetc.
  4. Monitor your diet. It must be balanced and he althy. Increase your intake of vitamins, they are found in fruits, vegetables, meat and fish products.
  5. It is allowed to take multivitamins to strengthen immunity. However, they should only be prescribed by your gynecologist, depending on the gestational age.

When to watch out?

temperature during pregnancy

Fever can be seen as more than just the first sign of early pregnancy. Many inflammatory processes in the body are also accompanied by temperature changes. Often, the body also reacts to the fact of conception with nasal congestion, drowsiness, chills and weakness. At this time, it is important not to confuse the onset of pregnancy with the onset of a cold or flu. After all, taking medication can provoke a miscarriage. Therefore, it is recommended to use folk remedies when such symptoms appear.

You should pay attention to the fact that the body's response to pregnancy remains stable, that is, does not worsen over time. While viral and colds tend to increase in symptoms. If after a few days you do not experience the appearance of additional symptoms, such as coughing, copious nasal discharge, watery eyes, scratchy or sore throat, then you should not worry.

When a woman begins to notice other signs of pregnancy along with an elevated body temperature, the first thing to do is a test.Then it is recommended to visit a gynecologist and be registered in the antenatal clinic.


Temperature in the first days of pregnancy, reaching 38 degrees, is dangerous for the fetus. In such a situation, immediate medical intervention is required. It is possible to bring down such a temperature only with paracetamol, since other drugs are contraindicated during the period of bearing a child.

There are certain rules for the use of medicines at the beginning of pregnancy:

  • antipyretic drugs should not be taken at temperatures below 38 degrees;
  • antibiotics are allowed only in extreme cases and under the strict supervision of a doctor;
  • recommended taking vitamin complexes and drugs that increase immunity;
  • in severe cases, it is allowed to take drugs that are contraindicated during pregnancy, under strict medical supervision.

Traditional medicine

lime tea

Also, the following traditional medicine will help alleviate the condition with fever in the first days of pregnancy:

  • wet rubdown with fresh lemon juice and vinegar;
  • compresses from fresh cabbage leaves;
  • milk with honey (dissolve 2 tsp of liquid honey in warm milk; drink in large sips of a glass 2 times a day; the main thing is that it is warm, not hot);
