Nuvaring and period (tmi warning please read)

Sooo this isn't first month on the Nuvaring. I took it out Sunday for my period. Today's Wednesday And I *think I got my period. I felt it in my stomach like normal and when I went to the bathroom i was bleeding but my blood is brown? Or I guess I should say brownish, I guess I'm just wondering if this is normal? Has anyone else experienced this?
