Low Grade Fever In Early Pregnancy


Low grade fever in early pregnancy is an indicator that something may be wrong with the developing fetus or mother. It is a fever that lasts longer than 38.3 degrees Celsius (101 degrees Fahrenheit). Generally, this temperature range is considered to be a low-grade fever and can be present in pregnant women due to hormonal changes, infections, immunological issues, or inflammation of the uterus. Furthermore, during early pregnancy it can also be caused by a condition known as hyperemesis gravidarum which is marked by excessive vomiting and nausea.

The risk factors associated with low grade fevers in early pregnancy include a history of miscarriage, preterm labor, and preeclampsia. Additionally, certain underlying medical conditions can also increase the chance of experiencing a low-grade fever such as diabetes mellitus type 1 and type 2, autoimmune disorders such as lupus or celiac disease. Dieting during pregnancy might lead to lower iron stores which can increase the risk for infections leading to fever. Lastly, increased physical activity during gestation may elevate one’s body temperature as well.

Symptoms of Low Grade Fever In Early Pregnancy

During early pregnancy, a low-grade fever may be caused by several factors. The most common symptoms associated with this condition include mild headaches, chills, fatigue, and body aches. Sweating or feeling flushed can also occur. In some cases, a low-grade fever is not associated with any other illness, but it can be caused by the hormonal changes of pregnancy.

If a low-grade fever persists for more than 24 hours or if the temperature is greater than 100 degrees Fahrenheit, contact your doctor as soon as possible to make sure there are no underlying causes for concern. A woman should also seek immediate medical attention if she experiences any of the following signs along with her fever: abdominal pain or cramping; nausea and vomiting; heavy bleeding from the vagina; a rash on the chest or face; difficulty breathing or chest pain; confusion; fainting; dizziness or lightheadedness; swelling in the hands, feet, or face; severe headaches; vision problems. While most cases of low grade fever in early pregnancy subside without treatment and prove to be harmless, it’s important to get checked out just in case there is an underlying cause which needs to be addressed by your physician.

How to Manage Low Grade Fever In Early Pregnancy

During pregnancy, a low grade fever is considered to be any temperature over 98.6°F (37°C). It is important to manage low grade fever in early pregnancy as it can be a sign of infection or other underlying health problems.

The best way to manage low grade fever in early pregnancy is to take safety precautions and contact your doctor right away. When experiencing a low-grade fever, stay hydrated by drinking plenty of fluids and rest as much as possible. Avoid eating foods that may further upset your digestive system and take an over-the-counter anti-inflammatory medication like ibuprofen if necessary. You should also avoid close contact with people who are ill or experiencing symptoms of any kind of infection or sickness. Additionally, avoid spending time in places where you believe there may be a contagion risk, such as crowded public spaces or unsanitary household items.

What Is a Cryptic Pregnancy

It is important to seek medical advice from your doctor when experiencing a low grade fever during early pregnancy as it can represent an underlying health issue that requires treatment or monitoring. Your doctor may decide to perform tests like blood work or an ultrasound to confirm the diagnosis so they can determine the best action going forward for both mother and child.

Treatment Options for Low Grade Fever In Early Pregnancy

When you experience a low grade fever in early pregnancy, it is important to contact your doctor so that he or she can assess the cause of your fever and decide whether any treatment is necessary. Your doctor may do some tests to help diagnose your condition and check for any infection during pregnancy. Some of these tests include temperature checks and blood tests for markers associated with hCG levels in urine.

If an infectious illness has caused the low grade fever, then prescribed medication such as antibiotics may be used to treat it. Additionally, the ingestion of probiotics may be recommended, as they can help reduce the severity of infections that cause fever during pregnancy due to their anti-inflammatory properties. Fluids such as electrolytes and adequate hydration should also be given to maintain adequate hydration and reduce fatigue during this period. Painkilling medications such as paracetamol should be taken with caution as they can cross the placental barrier with unknown consequences to the foetus. Supportive measures such as bed rest and avoidance of intense physical activity can also be taken if experiencing mild temperatures associated low grade fever in early pregnancy.

Risks of Untreated Low Grade Fever In Early Pregnancy

If a pregnant woman has an untreated low grade fever in early pregnancy, she may face significant risks. It is important to note that even a mild fever can result in a miscarriage or premature labor, and should be taken very seriously. Additionally, it could cause developmental complications for the baby, such as neurological problems later on in life. Furthermore, it may be associated with increased risk of birth defects, particularly those related to heart formation. Moreover, an elevated temperature can potentially lead to infection with bacteria like Listeria and E-coli which can also cause birth defects. Lastly, if not properly treated and managed, an uncontrolled fever could place undue stress on the mother and baby virtually throughout the entire pregnancy and develop into a full-blown infection.

Tips to Monitor Low Grade Fever In Early Pregnancy

During early pregnancy, it is important for women to be aware of low grade fever as a symptom of potentially serious illness. A low grade fever is any temperature between 99 degrees Fahrenheit and 100.3 degrees Fahrenheit. The most important tip in monitoring this type of fever is to accurately take the pregnant woman’s temperature either orally or rectally twice daily and report any changes or spikes to a health care provider. Other helpful tips include drinking plenty of fluids to stay hydrated, resting and avoiding strenuous physical activity, wearing loose-fitting clothing and avoiding extreme temperatures, eating nutritious foods rich in vitamins and minerals such as leafy greens, and taking acetaminophen (Tylenol) at the regular dose if necessary for comfort. If a woman experiences a fever higher than 100.3 degrees Fahrenheit or has flu-like symptoms like chills, splitting headaches, fatigue or body aches, she should contact her healthcare provider immediately for treatment evaluation.

What To Do When Experiencing Low Grade Fever In Early Pregnancy

If you are experiencing a low grade fever in early pregnancy, it is important to contact your doctor or midwife right away. Low grade fevers can be a sign of infection, which may have serious consequences if left untreated during pregnancy. Your doctor will likely ask questions about other symptoms, such as abdominal cramps, back pain, fatigue, or headaches. You should also tell your doctor where and when the fever was recorded (with a thermometer) and what measures you’ve taken so far to attempt to reduce it.

In most cases of low grade fever during pregnancy, the cause is usually minor and can be treated with medication such as ibuprofen or acetaminophen (Tylenol). Drinking plenty of fluids and getting lots of rest can also help alleviate many symptoms. If necessary, your healthcare provider may conduct lab tests to rule out any serious infections. Additionally, they may suggest ultrasound imaging to look for any signs of abnormal development in the fetus.


If you have a low grade fever in early pregnancy and it is left untreated, it could lead to more serious complications. Increasing temperatures could indicate infection of the amniotic sac or the membranes surrounding the fetus. It can also be a sign of preterm labor, vasa previa (a condition when the umbilical cord enters into the area of the cervix between the baby and placenta), septic shock, or miscarriage. Therefore, if you experience a low-grade fever in early pregnancy it is important to seek medical advice immediately for proper diagnosis and treatment.


Low grade fevers in early pregnancy can be troubling but usually aren’t a cause for concern. Mild temperature elevations may be caused by viral infections, like the flu or common cold, or illnesses such as urinary tract infections. In some cases, hormonal shifts can cause elevated body temperature, as well. However, women in early pregnancy should contact their doctor if they experience a low-grade fever lasting more than 24 hours, as this could indicate an underlying medical issue that needs to be addressed. Additionally, pregnant women should keep track of their temperature through regular checkups and inform their physicians if any changes are suspected. While low grade fevers do not typically pose a risk to the baby, treatments such as antibiotics may be necessary depending on the cause of the fever. It is important for expectant mothers to consult with professionals regarding safe and effective methods of treatment during pregnancy.
