Really sorry for anyone who goes through an mmc - especially with a first pg.
I had an mmc in with my third pregnancy. I was scanned at 5 weeks because I'd had a small amount of brown bleeding. I was told to come back in a week's time for another scan. This scan showed a blighted ovum and I was given an ERPC two days later. At the time I was heartbroken, but the procedure was actually very simple, done under general aneasthetic at my local hospital, and I was home that day (albeit slightly woozy from the aneasthetic). There was very little bleeding.
I went on to have a third DC a few years later with no problems.
Six yrs later, I became pregnant with a 4th baby. I bled at 6.5 wks and was sent for a scan. The scan revealed a sac that was "small for dates", and I was told to return for another scan a week later. I continued to bleed on and off, but the next scan revealed an embryo with a heartbeat (though still small for dates). I then began bleeding heavily and stopped feeling pregnant. I knew that I was miscarrying and asked for an ERPC (a scan revealed that the embryo no longer had a heartbeat). I was told that it was the hospital's policy to let women miscarry naturally (and obviously cheaper too!)
My 'natural' miscarriage was awful. It took over a week. I bled heavily, and the experience of passing the embryo and sac was not pleasant.
I went on to have a healthy 4th baby, who was conceived 6 mths after my mmc.
4 yrs later, I became accidentally pregnant again. After much agonising, I chose to have a medical abortion (using the abortion pill) at 7 weeks. Although technically a miscarriage, it was nothing like a natural miscarriage. The abortion pill stimulates strong cramps (much like early labour pains), and it was all over in about an hour - although I bled for a few weeks afterwards, but much like a normal period. I passed the embryo, all in one go, and straight down the loo (and no, I didn't look) - rather than in bits over a few days like my previous miscarriage.
So there are my three experiences of 'losing' a pregnancy. All of them very different, but all of them upsetting. On balance the ERPC was the least traumatic and the natural miscarriage was the most traumatic. Obviously the termination was the most psychologically difficult.
