"Early in pregnancy, a low fever is probably not a problem, but a high fever (over 103 degrees Fahrenheit) can be lethal for the baby.
The physiologic processes in early fetal development, such as protein activity, are temperature sensitive, and the entire fetal development process hinges on the right proteins getting turned on at the right time. If your body goes from 98.6 degrees to 103 degrees, it could keep the proteins from working properly and cause you to have a miscarriage.
Later in pregnancy, when your baby is fully formed and it's just a question of the baby getting bigger, fever isn't that much of a problem, unless it's caused by an intrauterine infection. To be safe, give your doctor a call if you have a fever that doesn't seem to be related to an illness."
I think it would be worth a call to your doctor. During my last pregnancy, I had an ingrown toe nail that got infected and caused me to have a fever and she seemed to think it was pretty important to take care of it. Pregnancy is weird like that. There's never any harm in double checking.

Second, I was told by my OB if I had a fever of 101 I was to go into l&d.
