First time TTC and charting BBC...

Natausha • 29, momma to a gorgeous little girl (1.7.2020) and 2 crazy dogs.

Does anyone have any insights on how to read my BBC chart? I've been temping at the same time every day... Set an alarm to wake me. I'm just not sure how to interpret what's happening. I didn't buy OPKs because it's the first month TTC.
