I am sorry that you are going through this, it is awful. I have had three ms all different.
My first was when DS was 2. I thought I was 12 weeks, had horrid flu and started bleeding very heavily in the night. Went to hospital wearing one of DS's nappies, after taking him to nursery. It had stopped developing at 9 weeks. As I was bleeding so heavily they did a erpc. As soon as I woke up and had the blood transfusion I went home.
The second was 8 years later, I had dd by then. I had been bleeding, a scan at 7 weeks showed everything was ok. At 12 week scan I knew something was wrong. They did not want to scan as I had one at 7 weeks. I insisted and they found no heartbeat and say it had stopped at 9 weeks. As I had bled so much on the first ms, they did another erpc and I went home when I woke up.
A year later I started bleeding at 10 weeks, this time I went to the hospital and insisted on a scan. It showed that development had stopped at 7 weeks. I went home and waited for nature to take its course. It took about two weeks. I was wearing pads. It happened in a business meeting, I could feel it coming out, no pain though. I was more worried about bleeding on the chair. The bleeding lasted a day.
After 2 Dc and 3 Mc, I decided that was enough.
It is awful to go through, but just do what feels right for you. If you can stay at home and wait, do so.
