Which do I use

Yesterday I woke up at 5am, reached for the thermometer the reading was 97.30, immediately fell back asleep until 8 or 9 never getting out of bed. When I got up at 8-9ish temp'd again 97.63. Same thing today, temp at 5 was 97.40, and then 97.84 at 8:30 Which temp's do I use. Also I did start Clomid this cycle CD 5-9, now on CD 17. It definitely causes hot flashes, so not sure if it's effecting my bbt.
