Missed miscarriage

Kt
After US and blood test I got a call from doc saying that I'm having missed miscarriage. I'm still in shock but I know I want it to end naturally. Google isn't helping but making me scared so I thought someone here has been thru the same. I'm 6 weeks. Bleeding for 6days now like period. No cramps but noticeable backache. What can I do or should I do. I know that doctor is trying to make an appointment for d&c and I just I'm not sure but I don't want anything to go wrong if I wait. Tmi I know but blood is bright red with tiny clots using pads every 3-4 hours. Can I get some advice please
