What body temperature can be in early pregnancy

The content of the article

Since the beginning of fertilization, in the first weeks an increased or decreased temperature during pregnancy in the early stages is not ruled out, which is caused by changes in the woman’s body. When the mercury column is in the range of 37-37.5 degrees, this is permissible and does not indicate pathologies. If other symptoms occur and when high rates last for a long time, you should be wary – this can cause a miscarriage or be a sign of any infections.

What is pregnancy temperature

How many degrees should the temperature be during pregnancy? In a healthy woman, the level of the thermometer varies between 36.6-37.7 ° С. So the body reacts to changes in the hormonal background. The indicator increases in the second phase of the cycle during the production of the hormone progesterone, which appears during pregnancy and is responsible for the preservation of the fetal egg. A temperature mark of about 37 ° C in the initial stages of gestation is considered normal. If subfebrile temperature is accompanied by fever, then this may be a sign of a cold or a dangerous infection..

Basal temperature during pregnancy

BT, or basal temperature, will tell a lot about women’s health: it will show fertile days (the most favorable for conception), the presence of ovulation, its absence, it will determine pregnancy. With its help, the work of the ovaries is evaluated, the development of pregnancy is monitored at the initial stages (12-14 weeks). BT measure:

  • vaginally;
  • orally;
  • rectally (in the rectum, immediately after waking up, without getting out of bed).

The period from the first day of the menstrual cycle until the onset of ovulation is considered the first phase of the cycle. BT should be at around 36.2 and 36.8 ° C. Throughout the second phase of the cycle, temperature fluctuations can be in a small range of 37-37.5 ° C. 2-3 days before menstruation, a decrease in basal temperature to 36.2-36.9 ° C is noted. If there is no sharp drop in the indicator and it remains at around 37.5 degrees – this is a sign of pregnancy. Increased temperature will be observed up to 4 months of gestation.

In the early stages

To fix a fertilized egg to the wall of the uterus, progesterone is needed. When the level of an important hormone rises in the body, the basal temperature during pregnancy in the early stages increases to 37.3 ° C. Measurement can be continued until the 16th week every day. The norm of values ​​is considered conditional and should not exactly repeat the generally accepted schedule. A slight increase does not mean pathology. Basal temperature in early pregnancy may be as follows:

  • 3rd week – from 37 to 37.7 ° C;
  • 4th week – 37.1-37.5 ° C;
  • from 5 to 11 weeks – high, but if the basal temperature is more than 38 ° C, immediately consult a doctor;
  • 12th week – not less than 37.0 and not more than 38 ° C.

Early fever during pregnancy

Hyperthermia accompanies pregnancy from the very beginning. In the first trimester, this condition is explained by changes in the woman’s body. Heat transfer slows down and temperature rises. Gynecologists are advised to take measurements twice a day – in the morning and in the evening. So you can determine the daily dynamics of changes. In the first trimester, body temperature during pregnancy in the early stages rises to 37.2 ° C, and this is normal. Throughout the entire period, it can remain at around 37 ° С – it is not necessary to bring down the temperature.

Temperature 37.5

To know what the temperature of pregnant women is in the early stages, doctors use 3 methods: measuring with an electronic thermometer, rectally and in the armpit. Using an electronic thermometer measure the indicator in the mouth (normal – 37.2 ° C). In the armpit, the temperature mark should not exceed 37 ° C. The thermometer shows 37.5 ° C when measuring rectal temperature in the anus. When pregnancy occurs without deviations, the change in indicators is as follows: from 37.1 to 37.5 ° C.

Temperature 38 during pregnancy

A significant increase in the indicator in the first trimester of pregnancy is considered unsafe. In most cases, the cause of the ailment is inflammatory diseases, but serious conditions that require immediate medical attention are not excluded. Temperature in early pregnancy above 38 is not considered normal. In order not to harm yourself and the unborn child, you should immediately call a doctor. All disorders that occur in the body since pregnancy affect the developing fetus.

Causes of fever

High rates indicate genitourinary or intestinal infections, acute respiratory viral infections and other diseases. An increase in the mercury column can reach 38.5 and be accompanied by symptoms of diseases: an increase in lymph nodes, a rash, pain in the sacrum and other ailments. In addition to a fever, ARVI is indicated by the symptoms of a cold: cough, runny nose, headaches. SARS in the initial stages leads to otitis media, pneumonia, tracheitis.

With intestinal infections, hyperthermia in a pregnant woman is accompanied by symptoms of fever, stool disorders. Diseases of the genitourinary system (cystitis, pyelonephritis) are noted by chills, pulling back pain, general intoxication, painful urination. Rashes on the skin at the initial stages of gestation indicate rubella, smallpox, or measles. An increased indicator on a thermometer is also a sign of an ectopic pregnancy..

Possible consequences

A temperature increase is a protective reaction of the body, but a significant excess of normal values ​​in the initial stages leads to irreversible complications. The first trimester is the period of the formation of the internal organs of the unborn baby, the bookmarks of the cardiovascular, digestive and nervous systems. A timely visit to a doctor will quickly determine, check the cause and begin treatment. A temperature increase in a pregnant woman leads to the following consequences:

  • increase the tone of the uterus;
  • the occurrence of malformations in the baby from the side of the eyeballs, jaw, palate and lips;
  • severe early toxicosis;
  • impaired protein synthesis;
  • decrease in blood supply to the placenta;
  • lag in the development of brain activity;
  • may provoke a miscarriage due to blood clots, clogging the vessels of the placenta;
  • premature birth due to early detachment of the placenta;
  • the threat of abortion, because the frequency of contraction of the uterine muscles increases;
  • intoxication of the body, which leads to pathology in the work of the cardiovascular system.

What to do at high temperature

It is justified to use methods of lowering the mercury column if the temperature is above 38 degrees at the beginning of pregnancy, in the later stages – after 37.5. Regarding the use of funds, always consult a doctor who will prescribe a safe treatment. Self-medication is dangerous to the health of the baby, who will soon be born. Medications that can be prescribed for pregnant women:

  • Paracetamol;
  • Panadol
  • Viburkol (homeopathic suppositories).

It is forbidden to take a medicine such as aspirin. If hyperthermia is caused by an infectious disease, then a cold treatment is needed. Doctors recommend using non-pharmacological methods that do not cause side effects:

  1. With hyperthermia associated with vasodilation, it is necessary to ventilate the room, put a moist compress on the forehead. Do not use alcohol, vinegar, cold water.
  2. If hyperthermia arose due to vasospasm, and hands and feet are cold and dry, then warming the body and drinking plenty of hot drinks will help..

Low temperature

Low temperature during early pregnancy is an indicator below 36.0. This condition is caused by various pathologies or easily eliminated situations. The latter include: insufficient nutrition of the expectant mother, overwork, stress, stress. If a woman fully eats, but there is a low level of sugar in the blood, a low temperature indicator – this indicates the development of diabetes. Other reasons leading to a decrease in temperature in a pregnant woman include:

  • decreased immunity;
  • transferred viral infections;
  • low hemoglobin;
  • missed pregnancy;
  • chronic diseases.
