Fever is a temporary increase in body temperature that occurs when your body tries to fight an illness or infection. A fever itself is not likely to cause any problems, but it usually indicates that there is something else going on in your body that could be a cause for concern, especially during pregnancy.

What is the reason of this?

Fever can have a number of different causes, such as the common cold, flu, sore throat, or other common illnesses that a pregnant or non-pregnant person may encounter. However, there are a number of infections and conditions that can be more common and serious that can also cause fever during pregnancy. These include:

UTI: Urinary tract infections are very common during pregnancy and affect 30% of women at some point in their 9-month pregnancy. UTIs are usually easily treated with antibiotics and plenty of fluids, but they can turn into dangerous kidney infections if left untreated.

Fifth disease: Caused by a virus, fifth disease is a common childhood illness that presents as a red rash along with fever and headache. Although usually mild, fifth disease during pregnancy can make it difficult for the baby to produce red blood cells, which can cause some serious problems. Fifth disease usually disappears on its own, but it's best for your healthcare provider to know and monitor it.

Tips

Being a little sick won't hurt your baby in any way, but certain conditions can be harmful, so it's best to contact with your healthcare provider if the fever lasts longer than 24 hours. You should also seek medical advice if your fever exceeds 38 degrees Celsius or if you notice a rash, severe headaches, difficulty in urinating, or other symptoms that you think are worth seeing, in addition to the fever.

If the only symptom you show is a mild fever, it's best to treat it at home as you would otherwise. Fever is the body's natural defense against viruses and bacteria, so unless there is something seriously wrong with it, it should pass in no time.
