What’s going on?

Okay so little background, I have PCOS, my boyfriend and I have decided to start trying to get pregnant. My last period was October 30th-November 2nd. My supposed ovulation day is the 13th (tomorrow). We had sex on a day that I was supposed to have medium chances and one day I was supposed to have high chances. Today I went to the bathroom and noticed blood? Could it be ovulation spotting? Implantation? Or did I get my period again since my cycle is so irregular due to the PCOS? This is a picture of what I saw, there’s not much and it’s fairly light in color…any advise?
