BBT chart help!

Jill

I am new to this, this is my first month tracking my BBT and I have no idea what any of it means! I’m pretty sure I ovulated sometime around the 4th because I had my usual symptoms of ovulation, but my ovulation tests kept coming back negative. One came back pretty high, but not positive. I think I just missed my surge though. After that one, they slowly got lighter each day and Glow keeps pushing back my ovulation day, although the original date was the 7th. Can anyone explain and help decipher my chart!?
