I had a MMC in similar circumstances- 10 weeks and measuring 6 weeks with no heartbeat.
I opted for the tablet once the 10 days had passed. However, I started bleeding naturally the night before I went in. When I went in, the nurses told me that as I started naturally I was probably best to let it continue. Days wants by. I knew something wasn't right because I was bleeding constantly and having periods of the Labour pains to pass clots. I kept ringing the EPU and then kept fobbing me off
One nurse said 'If you can't tolerate the pain, you need to go to A&E.'
4 weeks later I went back for my scan to check it had all gone. I was still bleeding and passing bits sporadically. I was also severely unwell by this point! Surprise surprise it hadn't all gone so I was booked in for the D&C the next.
Overnight, more bleeding and more large clots. They thought this must be it so scanned again the next morning and found there was still some there!!! So then I had the D&C. By this point I was severely anaemia and needed two units of blood. The consultant said I should never have been left to get into this state.
So all in all from the initial scan to returning to work took me 8 weeks. I was really really ill and it felt like nobody cared when I was saying something was wrong. It felt like something was stuck inside me, hard to explain.
I now always say to anybody who has a miscarriage, go and push for the D&C as your first choice. If I'd done that I would have been back at work within a couple of days and I wouldn't have got so ill!!
I'm so sorry you're going through this. It's incredibly cruel!
