What could this be?

Hi ladies.

Sorry for the TMI picture!!!

I am at 11dpo and I had this discharge today.

I had put a liner because in the morning I had a drop of a brownish discharge in my pad, now it looks like this - in person kind of looks pinkie-brown but I see in the picture maybe looks yellow?

It doesn’t smell and it doesn’t itch, no other symptom of sti.

Could this still be an infection or is just normal discharge?
