What is considered erratic BBT?
If your follicular phase temperature is consistently too high (above 97.8°) (See Figure 1.4), there are other considerations. Finally, BBT temperatures will fluctuate from day to day, this is normal, but if readings fluctuate more than . 3°F, this is considered an unstable follicular phase (See Figure 1.6).
Can BBT be wrong about ovulation?
BBT thermometers are not 100 percent accurate, and some women ovulate even without an increase in temperature. False readings can be caused by a variety of things, including waking up at different times in the morning.

An implantation dip is a one-day drop in your basal body temperature (BBT) that occurs during the luteal phase of the menstrual cycle (about seven to 10 days after ovulation).
Why does my temperature keep fluctuating?

What is a normal BBT before ovulation?
Before ovulation, a woman’s BBT averages between 97°F (36.1°C) and 97.5°F (36.4°C). After ovulation, it rises to 97.6°F (36.4°C) to 98.6°F (37°C).
Why does my BBT fluctuate so much?
The basal body temperature fluctuates daily, some days more than others. Changes in your routine can cause fluctuations as well – for example, changes in sleep, travel, and sickness can cause the basal body temperature to fluctuate.
Can you ovulate without a temp rise?

Does BBT go down before ovulation?
Your body temperature dips a bit just before your ovary releases an egg. Then, 24 hours after the egg’s release, your temperature rises and stays up for several days. Before ovulation, a woman’s BBT averages between 97°F (36.1°C) and 97.5°F (36.4°C). After ovulation, it rises to 97.6°F (36.4°C) to 98.6°F (37°C).
Why is my BBT low after ovulation?
The Connection Between Temperature & Progesterone During the follicular phase, which begins on the first day of your period and ends when you ovulate, most women experience naturally low progesterone levels — resulting in generally lower temperature readings.
