Maybe you got colds or the flu? You best have yourself checked by the doctor. Are you trying to conceive and taking any medications for this? It might also be a side effect. Can you give us an update?
Hi. Here is how our core body temp works. It has a base level and it begins to rise before we ovulate. Not much. Like a degree. But if you chart it, you see it clearly happen. It's biology. As your period is about to begin, it dips back down a degree to your baseline. If it does not dip back down, that is a sign of pregnancy. I tracked my cycle this way for 3 years and it followed this pattern the entire time. That doesn't sound like what you are describing. Hormones can fluctuate and give a hot flash. Ovulating and then either pregnancy or getting ready to start your period will fluctuate your hormones and we can get a hot flash then. However, a high fever? Probably not. maybe you caught a virus? Is this just a one cycle thing that happened?
