A. A fever during pregnancy is very concerning. She must be seen as an emergency. It is very important to get the fever down, and to be sure that she is not dehydrated, which she probably is. She must be seen immediately for these complaints. It may be a viral syndrome or it could be a bacterial infection such as a urinary tract infection, but please have her seen immediately. Any fever during pregnancy must be evaluated.
