My body temperature fluctuates everytime I measure orally it ranges between 97.6 to 99.2 mostly with weather variations such :- It is 8 am-  98.2° 11am- 98.4 12 pm- 98.6/98.8 2 pm- somewhere between 98.8 to 99.2 5 pm- 98.8 7pm- 98.6 10pm- 98.4 11:30pm- 97.8 3 am- 97.6 And it continues everyday, however the days when it is windy or rainy temperature in the afternoon is less to 98.4/98.6, I am quite healthy 26 year female with no other known disease or symptoms, Is it fever or do i need to worry about it??
