You may even find yourself asking, “how can you get a fever during your period?” Due to a rise in basal core body temperature during your menstrual cycle, low-grade fever during a period is normal, thanks to hormonal fluctuations.

Does your period raise your temperature?

During the menstrual cycle, body temperature rises and falls slightly due to the change in hormone levels. The shift in temperature is slight, yet significant. It requires a basal body thermometer to detect – that's a thermometer that shows two decimal places.

How much does your temperature rise during period?

It's lower in the first part of your cycle, and then rises when you ovulate. For most people, 96°– 98° Fahrenheit is their typical temperature before ovulation. After you ovulate, it goes up to 97°–99°F — about four-tenths of one degree higher than your usual temperature.
