I've been bleeding heavily for 3 1/2 weeks now. I had a 2 week break before I started bleeding this time. Before the break I bled for 8 weeks. This has happened many times before. I've been to 3 emergency rooms in the past 3 years and they just give me antibiotics or birth control pills and send me home. I'm currently taking birth control and it has no effect and 2 weeks into the first run of bleeding this time I took a weeks worth of Tetracycline which also had no effect. I am out of breath easily now and my blood pressure is low. How can I stop the bleeding I don't have enough blood to walk to the bathroom?
