Blood debris in amniotic fluid normal?

Based on setting: During pregnancy, it is not unusual to see "debris" in the amniotic fluid during ultrasound. This is likely related to vernix - a cheesy substane produced by the baby. On the other hand, bloody amniotic fluid that is actually seen can be normal, or it can be a sign of a complication called placental abruption. In either case, this should be clarified by the ob/gyn involved.
