During pregnancy, it is common for your body temperature to slightly increase due to hormonal changes and increased blood flow. A normal body temperature ranges between 97°F and 99°F, so a reading of 98.8°F falls within the normal range. However, if you are experiencing persistent or severe symptoms such as high fever (above 100.4°F), chills, or other signs of illness, it is important to consult your healthcare provider for further evaluation. They can assess your symptoms in the context of your pregnancy and provide appropriate guidance or treatment if necessary. It's always better to err on the side of caution when it comes to your health and the health of your baby during pregnancy.
