Your body temperature 99.5 high after 9th days have pass my ovulation is it sign of pregnancy?

While an elevated basal body temperature (BBT) can be a sign of ovulation, it is not a reliable indicator of pregnancy. A sustained BBT elevation for at least 18 days after ovulation can suggest pregnancy, but other factors can also affect BBT, such as illness, stress, and sleep deprivation.

To confirm pregnancy, it is best to take a home pregnancy test or visit a healthcare provider for a blood or urine pregnancy test.
