You know, I think it is best to stay with a gyno for gynecological issues. That's their specialty and they'll have more experience and are more adept at dealing with these problems. That long term bleeding is a big pain! Is full on bleeding or spotting? I assume you told your doctor about the depo shot. Diane 35 is banned in the United States. It was being misused. It's an acne medication that they were using for birth control . Not sure what country you live in. Depo is a different hormonal mix. Anyway, I think you need the guidance of your ob/gyn! What's the latest on this situation?
