When to call the doctor
Fever
Fever may be a sign of infection. For low-grade fevers (under 100oF), drinking plenty of fluids and taking a fever reducer such as acetaminophen may temporarily resolve the situation. The cause of the infection needs to be investigated by your doctor. Urinary tract and kidney infections are very common during pregnancy and may be a treatable cause of fever.
Exposure to certain viruses and childhood diseases will also cause fever. If you know you have been exposed to someone with a serious infection, bacterial or viral, or a childhood disease, talk to your doctor. Some of the "red flags" to watch out for are: cytomegalovirus, parvovirus B19 (Fifth’s disease), streptococcus infections, hepatitis, rubella (German measles), and varicella (chicken pox).The prolonged high temperatures associated with fevers, especially in the first trimester, may be dangerous to the developing embryo. Maternal fevers at an early stage in pregnancy may affect limb development and cause possible birth defects.
