A fever, particularly a high fever, may hurt your baby. Your baby relies on you for its temperature control. A prolonged high fever, especially in the first trimester (first 13 weeks), can affect a developing fetus.
To bring down a high fever, drink lots of liquids, take acetaminophen (TylenolÂ®) and dress appropriately to help you cool down. If your physician prescribes medication for a cold, bladder infection or other illness, take it as prescribed.
