Suggest Treatment For Heavy Menstruation Post Septate Uterus Surgery

I was diagnosed with a septate vagina and uterus. The septum was removed from my vagina and a vaginal band was also taken out in a second operation. The septum in my uterus remains. Since the surgery, my periods have been extremely heavy - on days two and three I am soaking through a large maternity pad (the sort worn after childbirth) every hour, I am soaking bed sheets during the night etc. I was not told that this would be the result and am wondering if it is going to carry on like this forever or will my periods return to normal?
