What is basal body temperature?

Basal body temperature (BBT) is a marker that the sympto-thermal community uses to track ovulation and fertility. It is an incredibly crucial component of confirming ovulation!

This is such a handy little measurement to have up our sleeves, because so many women don’t ovulate on day 14! Less than 10% of the menstruating population will have a cycle that is 28 days, and even less of that population of women will see a day 14 ovulation.

After ovulation occurs, we see a minimum .2 degree celsius increase in basal temperature which helps us confirm ovulation!
