The normal body temperature of the human body is between 36 and 37 degrees Celsius under the armpit, so the body temperature of 36.3 degrees Celsius belongs to the normal body temperature range. If you are monitoring your basal body temperature to determine whether you are ovulating or not, you should observe whether there is a rise in body temperature during ovulation based on your basal body temperature, rather than looking at the value of one body temperature alone. Therefore, there is no way to determine if you are pregnant based on a body temperature of 36.3 degrees Celsius. To determine whether you are pregnant or not, you should go to the hospital for ultrasound or blood HCG test.
