Bbt question

Is 98.6 degree Fahrenheit considered high or normal? Mine dipped down to about 97.5 a few days ago, but fo the past few days it's been 98.6 every morning.

Just wanting to know if that is what it runs in the 2WW.

If it helps at all, I'm on CD 28, and 10 DPO.

Four negative tests so far, I know i should wait a few more days.
