If you are pregnant and have a fever, it is important to monitor your symptoms closely. If the fever persists for 72 hours, if your condition worsens, or if there is no improvement after 7 days, you should seek medical attention. It is also recommended to stay hydrated by drinking plenty of fluids and consider using saline nasal solutions for sinus symptoms. Additionally, throat lozenges can provide relief for a sore throat. If you suspect you may have COVID-19, it is advisable to get tested and follow local health guidelines for testing and isolation.
