Hun, it could be because you haven't been BFing to help your uterus contract back down as you normally would after a baby (I'm so sorry I have to say that ) it is a bit of a worry that you are bleeding so heavily, and I'd be worried that your iron levels might be lower than they should be too. or it is possible that you have a little bit of retained placenta in there and that could be making you bleed heavier too. If at any point you think it is *too* heavy or you start to not feel well, I'd give the hospital a call
