Help pls! 8 DPO

Ariel • Currently pregnant with my rainbow baby boy through my 2nd round of IVF 🌈🤍 Angel mama

My regular BBT is about 97.60-97.80. Today I’m 8 DPO and my BBT is the highest it’s been which is 98.41. Could that be a good sign? I’m still pretty new to this! I took a pregnancy test this morning (I know it’s early) but I had a good feeling, it was negative, my ovulation test was at a 12.5 today which is considered to be high, according to my app
