Bleeding 7dpo?

I do have PCOS. This morning, I used the bathroom and found I'm bleeding? Looked almost about the size of a quarter, but I'm not sure if I'm actively bleeding yet or what is going on. It didn't seem to keep coming, iykwim. It was dark. Almost rust colored. Period? It would be about 7 days early I'm only on cd 21 or 22? I'm so confused. Ugh. Any thoughts or ideas would be awesome. Ha!
