Hemorrhaging after birth.

I am pregnant with my 3rd child and super excited, except terrified for the after birth(placenta.) With my first I hemorrhaged wasn't bad, my level was 9\12. With my second I was bleeding so bad I had to fight myself from blacking out and my score was a 3\12. My personal doctor was pissed I left without a blood transfusion, she said I shouldn't have left without it. My concern with this baby is I'm going to bleed out and leave my husband alone with our 3 kids. I know if I do die, my husband won't survive it and he knows he won't and what's going to happen to our kids.
