11 DPO Light Brown CM, On Progesterone Cream (w/Picture)

[Ttcourlittlem]

Hello all. I am currently 11 DPO, I ovulated late again this cycle ( CD 18 instead of 16) I started mt progesterone cream on 3dpo to make sure I ovulated. This is my first month using it and I have noticed that I have been super tired, my nipples hurt and now my boobs are super sore. I read that the cream can do that, but i thought it would also suppress AF, so Im a little confused as why my CM is light brown.

I only get brown CM the day before AF and Im not due for that for like 4/5. Could it be AF or IB? Is 11 dpo too late for IB?
