Hi All! I got a thermometer and started tracking my bbt yesterday. This morning I measured 36.68 C which is 98.024 F (figured this using a converter app). But I took another measurement right after changing the setting in the thermometer to show temp in F and it was 97.6. Which one would be correct? From tomorrow I am definitely going to set it firt to show in F before testing. How soon do you measure in the morning??
