The normal human body temperature oral (under the tongue) should be about 36.8°C (98.2°F), while the normal internal human body temperature (rectal, vaginal) should be at about 37.0°C (98.6°F).
Values of atleast 0.5°C above said temperature can be considered fever while temperatures of 1-2°C below normal temperature are known as 'Hypothermia' (body temperature too low).

Your body temperature is about right! Congratulations!
