Will you take a look?

Here’s my current chart. I do have long cycles as you can see. AF is due on Monday. What I’m wondering is, is there any chance yesterday dipping down so low could possibly be implantation dip? I typically temp 6:15-6:30 am, but this morning I woke up abruptly at 5:45. I went ahead and temped anyway in case I couldn’t fall back asleep. What do you think?

Wanted to edit to add: the crazy “mountains” before O is due to having the flu. Our whole house got hit including myself.
