Discharge question

Two days ago I noticed some brown discharge when I wiped. Very light didn’t even get on panty liner. Yesterday there was a tiny bit when I went to the restroom right after waking up then nothing the rest of the day. Today nothing until a few minutes ago. I go to the restroom and it’s still very light but it’s a little stringy.

I’m not sure where I’m at in a my cycle. I’m irregular. I’ve never had spotting before and I usually have cramps leading up to period but I don’t have that. I also have pcos. Pregnancy test negative. Ovulation test not faint but not positive
