Okay so my period ended ten days ago, but for the past three days I have been having dark brown discharge. I figured it was just old blood from my period. But yesterday it was a heck of a lot heavier with a reddish tint and clots. Every time I wiped and on my underwear. So much so I had to put on a pad. Woke up this morning and it’s still going on

Found out two months ago I have a 6x6 cyst on my right ovary. Could it have popped or leaked? Or is this just old blood and I shouldn’t worry?

Or is this something I should definitely call my doc on?
