How Effective Is Taking Noriday For Heavy Bleeding After Miscarriage?

I have been taking noriday for over a year and a half. I'd had a miscarriage and the bleeding didn't stop, so when I started noriday I was told that they would lighten my periods and probably even stop them. But my periods have been more regular than once a month at times, and also can be very heavy. Currently I have a period for 11 days, quite heavy. I have stopped taking noriday and am taking cyklokapron for 3 days now to stop the bleed. Awaiting gyno appointment, but worried about the non stopping bleed. Any help to offer?
