Rust colored blood

Jesie

I have pcos and so my periods are always irregular. I think I ovulated around the 28th but can't be sure cus my temp and everything ALWAYS fluctuates so much :/

Anyways...I thought I started last night cus I had some dark rust colored blood in my underwear.. so I grabbed a tampon and went to bed. Woke up this morning and there was like a drop of blood and that's it. Cleaned my house and a few hours later had another little bit on the panty liner I was wearing. Just like a smear.

Idk what it is because that normally doesn't happen
