When you list ranges of temperatures you should indicate the body part that is being tested, because an oral temperature reading will be different than a rectal reading. Also, the temperature readings you gave are slightly inaccurate; this [1] says that the maximum oral healthy early morning temperature is 98.8°F, and 99.9°F overall.
