Early morning temp: The basal body temperature is the temperature your body is at when you first wake up, before you get moving for the day. We use it to check for when your body releases an egg. It can only be measured with a special thermometer which reads temperature at a more accurate scale.

Basal Body Temp, BBT: Bbt, basal body temperature, is a woman's temperature at baseline, first thing in the morning, before arising out of bed. Bbt tends to be low in the first two weeks of the menstrual cycle, then rises just before ovulation, by about half a degree.

First AM Temp: Temp before getting up in the morning. Should be done in bed prior to sitting up. This temperature rises about 1/2 degree after ovulation. Not very accurate and very stressful for patients. If cycles are regular, 28 days then you most likely ovulate mid cycle, and if not, you should seek some help.

Not in: any systematic way. Humans are homeothermic, so we maintain our body temperatures regardless of outside conditions.

BBT: Basal body temperature is the taking of the oral temperature first thing in the morning approximately at the same time before even getting out of bed to do anything. Around midcycle or so about 1 to 2 days after ovulation the temperature will rise approximately 0.8 - 1.0° above the baseline. This rise signifies potential ovulation. The actual ovulation usually occurred midway between the rise.
