It is not uncommon for pregnant women to experience a mild fever during pregnancy. However, a temperature of 100.8 degrees Fahrenheit may be considered slightly elevated and should be monitored closely. If you are experiencing additional symptoms such as headache and severe body pain, it is important to consult with your healthcare provider as soon as possible. They will be able to assess your condition and provide appropriate guidance based on your individual circumstances. In some cases, a fever during pregnancy can indicate an underlying infection or illness that may require treatment. Your healthcare provider will also consider the potential risks to your baby and take necessary precautions to ensure their well-being. It is always better to err on the side of caution when it comes to the health of both you and your baby during pregnancy.
