Can you ovulate without a rise in BBT?

Be aware that many other factors can cause changes in the basal body temperature, like fever, alcohol, stress, certain medications, sleep disorders and even travel. Some women can also ovulate without having a temperature spike.

Does BBT always rise after ovulation?

BBT is slightly lower in the follicular phase (the first half of the menstrual cycle), and rises after ovulation and stays raised throughout the luteal phase (the second half of the menstrual cycle) (2,3).

Can you have low BBT and still be pregnant?

While you’re more likely to see a one-day temperature drop if you’re pregnant, it’s not a definitive sign of being pregnant. You might see a small dip on your chart almost every month on the seventh or eighth day after you ovulate.

Why is my BBT low before ovulation?

Basal body temperature usually drops right before ovulation, then increases rapidly. … In the late luteal phase, when the corpus luteum regresses and serum progesterone level decreases, the BBT returns to the lower range either one to two days before or just at the onset of menstrual bleeding.

How do I know if I ovulated with BBT?

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).
