I have been using the Nuvaring to skip my periods since about July. I took it out for a week in September to have a period after I noticed constant spotting. It's happened again now only I'm not scheduled to remove the ring until next week. I have been bleeding consistently as if it were a light period for 7 days now, though, and there is light cramping (I never get cramps except on the first or second day of a regular period) and all the blood has been old blood, all brown, some pink, no red like the usual periods. Is this cause for concern? Why is all the blood so dark and why is this breakthrough so persistent as opposed to the usual spotting? What course of action should I take now?
