1- HIGH FEVER
During pregnancy, you may feel flushed or more hot than normal. It can be hard to tell if you are actually experiencing a fever or not. Hormonal fluctuations and your baby, in general, will cause a little more heat to your body.
Thankfully a mild fever, under 100 degrees is unlikely to have any sort of effect on your pregnancy.
Most generally, A temperature of 100-101 degrees is considered a fever in pregnancy. If your temperature reaches 101 degrees you should call your healthcare provider immediately, no matter what time it is.
If your temperature is only 100 degrees with no accompanying symptoms, you can try to bring the fever down and call your doctor if the fever persists.
