Missed my peak/positive?

How do you know if you missed your peak/positive? I’ve been testing for about 9 days now (started on CD6 since that was the day after my period ended) and none of my opks have been positive. I’ve had a few that were close but those days are CD8 and CD11. I’m still testing today and it’s still not positive. I’ve been testing 3 times throughout the day. My schedule has gotten kinda wonky and off track too but still I’ve been testing. I don’t know if I missed it or not because my cycles are so irregular.

Here’s my chart. Also I’m very aware on how opks work and that the test line needs to be as dark or darker then the control line. So I know all of these are negative.
