On Off Period for 5 weeks after taking YAZ for 3 days and qu

I began taking YAZ in December and only took it for a few days. I started having a period a few days later that was very dark. It stopped after a few days but then began again with a bright red and some dark. This has been going on for about 5 weeks. I am very fatigued, and emotional. My Dr. does not seem to care and has not responded to my calls. I am thinking of going to the ER. Has anyone had similar issues with a period that will not stop?
