Have no idea how to read my bbt chart- newbie

[AliceM6]

Hi I was wondering if there were any bbt experts here as this is the first month tracking my bbt chart and all different apps say different things.
Could somebody tell me what it means and if I have done enough this month or did I miss ov?
How come on pre mom I have a B on the first spike that dipped again? And more importantly why was my LH peak AFTER my temp drop? I thought it was before. Any idea when I actually ov? Thank you.

You've got lots of triangles which suggests you're taking your readings at different times which will affect the accuracy.
I only use cheap opks, so tend to ovulate on the day of my positive opk, don't really know much about one's that show high and peak fertility.
It does look like cd10 could be ovulation, you post ovulation temps aren't that high though and you've got dashed crosshairs on the fertility friend chart so keep temping, it might change your day with more information.

Thank you for your reply @VenusStarr

The reason why I’ve got triangle is because I was just using one app and then downloaded some more and inputted the information across and didn’t change the times so this is why they look inconsistent.
I will continue to temp and see if anything changes.
Thank you!
