Amy8702 is right is different for everyone. I actually bled for one day & spotted for 2 days when I supposely miscarriaged. I'm still on the process of making sure my bean baby was flushed out or maybe God has other plans for me. We will see but may God be with you & good luck ma.
Everyone is different when it comes to the bleeding, for me with all my miscarriages from day 1 of bleeding it was usually 10 days. My friend just had bleeding for 5 weeks before it stop. D&C's you're usually not awake for, afterwards you may have some cramping and should stop bleeding within 7-10 days. I'm sorry for your loss.
