Cycle day 20 medium spotting...?

So question for you guys. I have spotting the seems like a very light period. Started today and it's cycle day 20. My cycles are typically controlled by provera because of how drastic my hormone imbalance is. So because of that I'm typically 32 day cycles.

Has anyone else experienced cycle day 20 bleeding? Mine was maybe the size of quarter and brown with some pink mixed in. It just happened so I'm not sure if it will become heavier I'm just not used to having bleeding without the provera....

Any thoughts before I call up to our RE?

Thanks.
