I had a high fever early in my first pregnancy. As long as the fever isn't too high and for several days straight, that is what they were worried about. That is such a low fever I wouldn't even take Tylenol, just let your body fight the virus. COngrats!
I think that is a fairly low grade fever. Perhaps a bit of a cold or a touch of the flu? it is completely safe to take tylenol during pregnancy, so perhaps try that and lots of fluids. Never a bad idea to check with your Dr. As far as I know there is no link between low grade fever and miscarriage. A very high fever, perhaps, but low grade, not as far as I know. Get some rest, drink lots of fluids and if you are feeling achy, it's fine to take tylenol. Hope you feel better soon.
