See a doctor: Heavy bleeding while taking birth control pills is not common, and could be a sign that you are pregnant, have anatomic abnormality (like uterine fibroid), or that the bleeding is not coming from inside the uterus and is coming from the cervix instead.
Changing brands should not make any difference.
