Temperature Spikes in Pregnancy

One of the most sensitive indicators of human health is body temperature. It increases with viral and infectious diseases, chronic processes, inflammations, and other reasons.

Temperature norms change during pregnancy. A slight excess of the usual indicator of 36.6 ° C is permissible. The temperature of a pregnant woman can be considered acceptable at 37-37.4 ° C. A sharp and more significant increase in the body temperature of a pregnant woman goes beyond the normal state.

When Do Temperature Spikes Start in Pregnancy?

Permissible elevated temperatures may appear in the first days after conception. Temperature fluctuations are typical for the first trimester. The beginning of changes in temperature indicators can be a sharp rise in progesterone. It is the main stimulant of most of the symptoms of pregnancy.

Changes in the body temperature of a woman in position can begin with viral diseases. This is manifested in chills or a sensation of heat.


The body temperature of a pregnant woman rises in the first trimester. This applies to weeks 1 and 2 of pregnancy. The temperature can reach 37.2–37.4 °С.

This increase in body temperature is due to an increase in the hormone progesterone. There should be no other temperature spikes if the woman does not get sick with viral and infectious diseases during pregnancy.

Temperature spikes

When will it end?

Temperature fluctuations during pregnancy are characteristic only of the first trimester. They last up to 2nd week in the absence of diseases. You can forget about possible temperature changes after the end of the first trimester.

Subfebrile temperature may persist. Sometimes it remains until birth (39–40 weeks). The reason for this phenomenon is difficult to establish. It is rather an individual feature of the mother’s body.

How Does it Feel?

How a woman will feel a temperature rise depends on her subjective sensitivity. Some can catch an increase in the norm by one mark on the thermometer, while others will not immediately notice the high temperature.

A variety of sensations are likely with an increase in temperature: fever, chills, sweating, headache, weakness, and drowsiness. It all depends on the degree of reaction of each woman.


A sharp and significant rise in temperature will be felt as intense heat and sometimes chills. The pregnant woman will feel bad, she will have weakness and fatigue. Such symptoms are characteristic of increased rates of permissible norms when the mark goes beyond 37.4 ° C.


A slight increase in temperature may not be felt at all by a pregnant woman. It is expressed in easy fatigue and sweating. The woman does not leave the usual rhythm of life and feels satisfied.

Watch for symptoms at elevated body temperature. The disease may be the cause of high fever.

Prevention methods

It is sometimes very difficult to prevent the appearance of some symptoms during pregnancy. This also applies to temperature spikes. It is difficult to predict whether this symptom will be in a pregnant woman or not. It is necessary to monitor health before conception and know all the features of your body.

Several preventive measures will help to avoid possible temperature spikes during the period of bearing a child:

Boost your immunity

Walk more in the fresh air, sleep at least 8 hours a day, eat right, and play sports. This will boost the body’s immune system. The reasons for the strong temperature rise will disappear. Your well-being will improve and the risk of viral diseases will decrease.

Avoid overheating

Dress for the weather and according to your body temperature. Do not take hot baths or showers. Do not stay in the open sun for a long time. Stop sunbathing and visit the sauna, solarium, and more. Stay in comfortable conditions for your body.

Treat the body

Get treated for chronic diseases before conception if you have them. Do not let them go into the acute stage. Make sure that the problem does not appear during the gestation period. Reduce all risks with preventive measures. Chronic diseases are a common cause of jumps in body temperature.

Why Temperature Spikes happen in Pregnancy?

The change in body temperature during pregnancy is due to hormonal changes or as a symptom of a disease. A sharp increase in the level of progesterone in the blood is observed in the first trimester. This is the reason for the increased temperature within the permissible values ​​​​of 37–37.4 ° С.

Body temperature goes far beyond 37.4 °C when it is elevated due to illness. If the indicator on the thermometer is close to 38 ° C, this is not the norm, and treatment is required for the accompanying symptoms. These temperatures can be caused by viruses, infections, pneumonia, or an ectopic pregnancy.

If the temperature is below 36.6 ° C, the cause may be toxicosis and exhaustion of the body, as well as reduced immunity.


Sometimes it is difficult to find gentle remedies for some symptoms. Temperature fluctuations are not easy to eliminate. It is always better to call an ambulance if the temperature rises to a high enough mark. Conservative methods and means will not help in such a situation. High temperature is extremely dangerous for the fetus.


This is the most common means of protection against high temperatures. It should not be used on its own. Only a doctor can prescribe any drugs during the period of gestation. Any medical intervention without consulting a specialist can adversely affect pregnancy. Bringing down the temperature to 38 ° C is not worth it if your health is satisfactory.


You need to drink plenty of water if the high temperature is slightly higher than the allowable rate. It is consumed in small sips on an ongoing basis every 15 minutes. This will prevent dehydration and make you feel better. It is acceptable to take a cool shower or a cold foot bath. Apply the method of rubbing the body with cool water.

Fresh air and bed rest

Open the window and get into bed. Do not cover yourself with a warm blanket if there is no chill. Being in a calm state will reduce physical activity and body temperature. This method works with a slight excess of the norms of permissible temperature values.


Body temperature during pregnancy should be measured in the morning and evening. Such control will allow you to identify the dynamics and solve the problem faster.

It is worth immediately calling an ambulance if there are no visible symptoms of a viral disease and the body temperature rises and reaches maximum values. This condition is often caused by an ectopic pregnancy. It is worth contacting a doctor even with small increases in temperature that appear on an ongoing basis.

What Not to Do

Sometimes the actions taken can harm the body of the mother and child more than inaction. Treat your condition during the gestation period with more care and caution. Any measures to combat the symptom should be discussed with the doctor who is leading the pregnancy.


Panic is the worst enemy for making an adequate decision. You can make a lot of mistakes in this state. Control yourself or ask for help from loved ones.

Take medicine from your first aid kit

Any inconsistent and thoughtless taking of medicines can adversely affect the health of the child. It is necessary to take medicines only in extreme cases.

Continue work

Take time off home if a strong jump in temperature caught you at work. You need rest. Physical and mental stress can aggravate the situation.
