Basal body temperature (BBT) is our lowest temperature during rest, which is usually during the time we're sleeping.
This is the reason why BBT should be taken before getting out of bed for accurate fertility charting. Ovulation causes one
half to one-degree rise in BBT, so monitoring BBT helps provide information on the best time for conception.
Note:
The calculated forecasts of Home Care may not be accurate and should not be used to prevent unwanted pregnancy. The
forecast accuracy depends on a number of factors including how regular one’s cycle length is, how many periods have been
measured with the app. Anxiety, stress, age and other factors can also affect one’s cycle from month to month.
