How many weeks pregnant are you?? The bleeding is much greater around 10+ weeks. You don't need to go to hospital to miscarry but you do need to monitor the bleeding. It shouldn't be more than a heavy period for blood loss and the pain can vary between individuals. You can take pain relief - whatever you normally do.

How long - unfortunately this is an unanswerable question. For some, the entire sac is passed intact. For others it occurs in stages and can take longer. Days to weeks.

Will you need the D&C - it depends on what happens with you over the next few days. Speak with your doctor on Monday. They may want a repeat ultrasound and if your body has completely managed your miscarriage on its own, they will try to avoid surgery.

I am so sorry
