Hello Thanks for your query. The birth control has obviously failed to control the heavy periods. You could be requiring a higher dose, or a different preparation of hormones altogether. Also, a gynecological evaluation should be done to rule out the cause of menorrhagia ( heavy menstrual bleeding ). If no obvious cause like fibroids, cysts, etc is found, then hormones should work in regulating your periods. Please consult your doctor to prescribe a different brand , and one with a higher hormonal content. If a pelvic ultrasound has not been done, then please get it done. Take care.
