2 days late.. but definitely ovulated?

I had brown spotting on 9 dpo and 10 dpo then nothing.... I have had mild cramps since nothing crazy and minor lower back aches. And normally if I spot before my period I never stop spotting it just gets heavier and turns into a period.

Fast forward to today, I am now 13 dpo and AF was due yesterday... I have had no spotting since 10 dpo and on 12 dpo I had light brown cm that was sticky (not like normal spotting). My boobs hurt pretty bad but now just mildy achy.

What do you guys think? If I did have IB on 9/10 dpo then does it make sense if I still haven’t gotten a BFP? Here is a hpt from this morning and a graph of my temps... just trying to figure out what is going on!
