Confused about BBT

MM • 30. Married. Pug mom. 👼🏻 7/14/20. 👶🏻 8/5/21 🌈

New at this, but what’s a good temperature for ovulation? So it was 97.79 the other day and then it dropped to 97.05 the next day. I’m on cycle day 16, in my fertile week according to the app. Been having some egg white CM too. Had sex today just to cover my bases.
