What is happening??

So I had my peak and as lh dropped and bbt started rising I stopped tracking. Since my peak I’ve been cramping and spotting dark red/brown. Since 1dpo I’ve been really crampy and brown spotting. I have pcos and struggle with my progesterone. I was planning to start progesterone today but worried I may have not ovulated.

Judging by my symptoms would you say this is due to low progesterone or could it be I haven’t ovulated?
