Newbie with BBT

Hey Everyone!

I hope everyone is being safe during these hard times. I have recently bought a $50 fancy Bluetooth tracking thermometer 🤦🏻‍♀️ then it got delivered after I ovulated🙄. I’m trying to read and figure out about temping, but I feel like I see/read good thing/bad things.

Can anyone give me advice with temping, and what to look for? Is it reliable? How does it fall hand in hand with ovulating? If I’m pregnant will I be able to tell via temping? When do I start temping or should I temp everyday?
