First time doing bbt

Ciera

Hey guys, just looking for some help! Once AF arrives in a few days, I'll be doing bbt for the first time and I'm hoping for some answers to questions I have.

1) Do I temp everyday from CD1?

2) Does tracking the bbt help find ovulation day more accurately than ovulation tests?

3) Even doing bbt is it best to still do ovulation tests to see if that correlates with peaking LH and temp?

4) Do you use it vaginally for the best reading or is oral best?

TIA x
