By doing a scan aka ultrasound, she can check for cysts and things like that. It is probably a really good idea to have it done if you are having that much brown discharge.
I don't really have any suggestions, but I have been through it. My Dr performed a D&C on me last year to give me a "clean" start because I was going through the same thing. I've had regular periods and no old blood discharge for 15 months now.
