New to temping! Does this look ok?

I started temping at the end of my last cycle, which told me nothing, but I’ve continued through this one!

Negative pregnancy test this morning on 9dpo.

I didn’t have ovulation symptoms (cramping) until the day of my spike which the app called 1dpo. Could I really only be 8dpo based on cramping symptoms?

Does everything on my chart look ok? I didn’t have a 3 consecutive day temp rise at first…. would that mean I didn’t actually ovulate?

Any chance of getting a positive still?
