Heavy periods (TMI)

I lost a baby in March at 9w2d ( following a loss in November 2013) and ever since my periods have been very heavy, this month they seem to be extreme with a lot of clotting, I am going through 2 night time pads an hour- have tried incontance pads but the same thing I only get about 2/3 hours use and that's them soaked through.. Does anyone have any tips on how to make it stop being so heavy or even how to deal with it. 
Sorry for the tmi x
