How high can your temperature be to be pregnant?

A slight increase in body temperature can occur during pregnancy due to hormonal changes, typically ranging from about 97.5°F to 100.4°F (36.4°C to 38°C). However, a fever, defined as a body temperature above 100.4°F (38°C), is not normal and may indicate an infection or other health issue that requires attention. If you're concerned about your temperature and its relation to pregnancy, it's best to consult a healthcare professional.
