For those who have been through a miscarriage, please help me!

I found out the baby stopped growing last Tuesday, at 6w3d. I had a follow up yesterday and the baby is still the same. I would be 10w3d today, so I've been carrying this baby for 4 weeks already. I've been spotting only when I wipe for 11 days & then yesterday after the ultrasound, I thought it was going to happen because I had to use a panty liner, but then today, it's just when I wipe again. I'm not trying to sound bad, like i don't care about the baby, i do, but i know it's gone. It's just I want to do this naturally, but I don't know why it's taking so long. I was so excited to be having this baby, and now the blood everyday is just a daily reminder that it's gone. My question is, how long will this natural process take? It's already been 4 weeks since the baby has died. Please no negative comments, I'm having a horrible time going through this and to those who respond, thanks in advance.
