Misscariage and dnc. how long will my daughter be in the hospital?

Just lost a baby a 20 weeks , had to be in hospital for 4 days and I am steal on bed rest even two weeks after. It all depends on why she lost the baby. Our baby had a blood infusion and gave it to me so that is why it has taken so long. Go back to Dr. in AM so maybe I'll be able to get back to life.
