Can you use a basal thermometer orally?
You can use a special thermometer designed for basal body temperature, or a digital oral thermometer. You can take an oral, vaginal, or rectal reading. Just be sure to use the same method each time.
Is basal temperature the same as body temperature?
Basal body temperature is the body's at-rest temperature. It is the lowest temperature of the human body and ranges from 97.8-98.2 degrees Fahrenheit. Basal body temperature differs from body temperature in when and where each is measured.
Are basal thermometers more accurate?
Unlike regular thermometers, which are accurate only to 0.2 degree, basal thermometers are accurate to 0.1 degree. While basal body temperature can be recorded orally, a vaginal or rectal measurement may be more accurate, so consider thermometers with a soft and flexible tip and quick reading time.
Which thermometer is the best?
Best thermometer overall: iProven Forehead and Ear Thermometer DMT-489. Best thermometer on a budget: Vicks Comfort Flex Thermometer. Best infrared non-contact thermometer: iHealth No-Touch Forehead Thermometer PT3. Best thermometer for daily testing: Kinsa Quick Care Smart Thermometer.

What will BBT be if pregnant?
After the female egg cell is released at ovulation, BBT increases to between 97.6°F (36.4°C) and 98.6°F (37°C). Basal body temperature will drop again if pregnancy doesn't happen. This temperature drop causes the uterus lining to shed, causing a period to start, and a new menstrual cycle to begin.
What is a high BBT?

What is a low basal body temperature?
A pre-ovulatory basal body temperature that is consistently below 97.5 F / 36.4 C can be indicative of hypothyroidism (note that this range is based on oral temps and axillary measurements may be different). Other signs of hypothyroidism include: Fatigue.
