Hey Mom2Hope congrats!!!!
Definitely see your dr on Monday, but until then, cooling your body is the way to go at that kind of fever level. Even if it's uncomfortable, a cool bath will help. Sleeping with no covers, windows open, that kind of thing. I've had to do it with babies and it's horrible -- they cry and cry -- but ultimately, the temperature goes down, and all is good.
Tylenol (just plain tylenol, nothing added) is meant to be safe during pregnancy, so I'd use that too.
Good luck and Happy and Healthy 9 months!!!
