Help?!?

Ok, so aunt Flo is 8 days late (I think...) let me explain... I have PCOS... so my periods are SUPER irregular usually... however, the past 2 months it's showed up on time. Now this month, I had super light spotting on the day I was supposed to start. Enough to show up on TP but nothing on tampon or pad.... ok, cool! Though maybe I missed her. Then the 26th I had a little more spotting, same kind. Then today just a bit more spotting... should I chalk it up to just a weird period or do you think I mightve missed it?
