What IS THIS!?!

I was suppose to have AF start 12/11 and it didn’t come I had swollen boobs, a cold, a faint positive that didn’t seem to get darker, but I have pcos so I know I ovulate late. I thought af was gonna show up because I started spotting 12/23 the tiniest bit but I started spotting i would say officially 12/24. It recently stopped. This is the most it’s ever been in the picture! (not a full period). I have never had this happen before. What do you think??!
