I'm so sorry that you're going through this SingaVera, the limbo stage was really the worst part of my missed miscarriages.
My first, when I was 39, was discovered at around 8 weeks, no heartbeat at all, so I was told to come back in a week and I opted for an ERPC/MVA under local anaesthetic. It did hurt a fair bit, but it was quick. The consultant who carried out the procedure was incredibly kind and stopped whenever I asked him to. There was also a nurse who talked to me during the procedure, and my dp stayed and held my hand throughout. Physical recovery was quick, I went to a festival three days later, and I had minimal bleeding. My period returned exactly 4 weeks later.
I conceived six months later and had my DD with no issues.
Sadly in Dec 2016, I had another early scan at around 8 weeks and the embryo was too small (I was sure of my dates). I had two weeks of waiting until the heartbeat stopped, and opted for an MVA under local anaesthetic again. They use ultrasound to guide them, and the only downside is the noise of the vacuum. You get given a tablet or pessary an hour or so before to soften up the cervix. I had actually had some bleeding prior to the op, but there was still lots of tissue remaining so they went ahead with it anyway.
Last May I lost another pregnancy at 14 weeks due to a trisomy, and this time I opted for an ERPC under general anaesthetic. It was absolutely fine, well as fine as it could be. It's a very light general, your're not under for very long. Again, minimal bleeding or discomfort afterwards.
I always opted for surgical management because I know so many people who have had complications from natural management and ended up having erpcs anyway. I also couldn't stand any more waiting, and wanted to get back to normal physically as soon as possible. My body also seems very unwilling to miscarry on its own, so it seemed the best option for me, it's a very personal thing though.
I hope it all goes ok for you, whichever route you take, and that you have good support. 
@Laurel543 Many congratulations on your pregnancy. You've inspired me to not give up hope completely.
