Hello there everyone,
I have been watching this thread for a while now and I'm so sorry to you all who have had to go through this, some multiple times. 
I think I just want to share my experience in case it helps anyone reading here silently now or in the future.
I had a missed miscarriage and like others on here was struggling to make a decision about what to do as it just wasn't happening naturally. I went into hospital on Sunday morning to talk through the options again as I was just past 12 weeks, baby had stopped growing at 6 and we found out at 8 (confirmed by a second scan the week after). So it had been a while and I'd had no spotting, just some light cramps. The doctor on Sunday morning told me they definitely felt it was time to intervene, and that due to the risk of infection now they would like to keep me in hospital. I realised I needed to change how I was thinking, and so decided on medical management (misoprostol) first but then knowing that surgery was a very real possibility and would be the next step.
I had the misoprostol put directly onto my cervix at 3pm. By 6pm the cramps were quite bad but a nurse very kindly and secretly made up my hot water bottle! Suddenly at around 8.30pm they became unbearable. I was in the most excruciating pain I've ever been in (and I have two boys aged 4 & 2 so can say this was much worse than their labours). I also felt like I needed to push. I went and squatted on the toilet and passed a few clots, then was finally brought some dihydrocodeine. This took about 2 hours to kick in and they were the worst two hours of my life. The pain was agonising. However - as soon as it did, everything became so much more manageable. The bleeding continued like a period, and I was able to get some rest (waking for obs and another dihydrocodeine) until around 5am, when the pain woke me up and I felt I needed to push. I went and squatted over the toilet again and passed the placenta and pea sized sac with our tiny babe in. I was in a lot of shock as I wasn't expecting there to be so much placenta/obvious tissue. I had prepared myself for it to be much worse than a heavy period, but I am so pleased we were in hospital otherwise we would have completely freaked out.
I cried and cried and cried at this point as the relief I felt was immense - I just knew that was all of it. I didn't feel at all nauseous or unwell like I had done since the pregnancy symptoms started at Christmas, but of course I would have taken months of sickness if it meant we could have held our baby in our arms come the summer.
We were so well looked after at the hospital, there was just the one nurse who hadn't quite been as on it as the rest but it is what it is. We were very fortunate to receive the care and compassion that we did.
I spotted for most of Monday morning then by the afternoon it got a little heavier and since then I have been bleeding lightly like a normal period.
We were able to bring our tiny baby home with us which helped me feel I wasn't leaving the hospital completely empty. I carried my little box out with the certificate of foetal remains - which feels like an official acknowledgment of our baby. We are going to bury her in a lovely large plant pot we have bought for a beautiful plant.
The hospital sent me home with more dihydrocodeine which I have felt the need to take each night so I'm not waking up due to the ache. I am having regular period cramps but my whole abdomen is incredibly incredibly sore. However, I feel quite well in myself. Pregnancy does generally wipe me out and my symptoms didn't really ease too much after the baby had stopped growing so it's been a tough few weeks, but I'm about to do the Pre-School run this morning, and while I'll definitely also need to nap when my 2yo naps, and won't be giving up the pain killers just yet, I'm amazed at what my body has done.
I was really struggling with the missed miscarriage and how my body hadn't realised the pregnancy wasn't viable, but actually looking at it in the view of actually my body was doing all it could to protect the pregnancy has helped.
I'm glad I didn't rush into a decision, too, and felt supported by the nurses on the gynaecology unit. They respected all our choices and honoured our baby by referring to her as she/her like we were doing so we didn't have anyone say anything too clinical.
I am crying quite a lot, and I don't know when I'll return to work (my job isn't one where my work will distract me from what has happened, it's too emotive), but just taking it hour by hour, then I guess day by day. @Tor88 that's my only advice to you I'm afraid. Hour by hour and day by day. And crying! I have made small goals for each day, do skin care, wear jeans (instead of joggers!!), today is leave the house for a short walk.
Love to you all, and, I'm a pray-er, so please know I'm praying for each one of you and your families too.
