Hi basgetti. First and foremost, I am so so sorry for your loss.
I too had a MMC about 3 weeks ago, found after a bit of brownish red bleeding at 11 weeks, baby stopped developing at 6. I was sent home to await a follow up scan a week later because they wanted to rule out my dates being wrong but started to miscarry naturally a few days later.
Everyone's experience will vary but in my case, I had about 4 days of very light brownish bleeding with cramps getting progressively stronger, most noticeably at night time.
I started getting bright red bleeding in fairly significant quantities (more than a typical period but not gushing or anything scary like that) on the night of day 5 post scan and the cramps got much much worse, but manageable with ibuprofen. Spent a lot of time that night just sat on the loo with DH sitting with me watching tv on his ipad, basically anything to distract myself.
The following day/eve was the worst of the bunch cramps wise. I'd say they were more like contractions really, I was genuinely in agony for a good 5 hours or so, DH ended up calling 111 who dispatched an ambulance. Tbh that wasnt really needed, but he was worrying and I was in no fit state to talk to the phone operator. The paramedics were very lovely and did offer to take me in to a&e but I figured I was in the worst of it by then and would rather stay home. They advised to alternative ibuprofen and codeine/paracetamol so I could take a painkiller every 2 hrs instead of 4 and that definitely helped, although it really was an ordeal.
Now it's over, I have very limited and numbed memories of that evening, which is probably a good thing. Lots of women miscarry naturally without as much pain but I was unlucky I guess.
Even with hindsight I still don't know if I would have preferred a D&C or medical management tbh. I hate hospitals, and the thought of being anywhere near maternity for such a shit reason seemed too distressing. As painful as it was, being at home was comforting and the fact my body did what it was meant to and I saw it through 'to the end' so to speak helped too.
Whichever way you choose to manage it, it's going to be unpleasant but its entirely your choice, there's a great thread on the practicalities of managing a MC at home here.
Whatever you decide, I wish you a speedy recovery and hope you are feeling better soon. Mumsnet is a great place to come and vent.
