@Slk3558 I would ask about MVA. It's a less invasive option than D&C and it's done under local anaesthetic. It may be that your local hospital doesn't offer it, but in such case they should tell you about other hospitals in your area that do.
Having said that, if your sac is collapsed and you're spotting, this is a sign of a miscarriage starting naturally. I think I had some spotting too in my blighted ovum pregnancy in a week before my MVA but it didn't progress naturally, I'm afraid. Just give it time and be kind to yourself.
It also sounds you're in a frame of mind of getting things restarted asap. Word of advice after 3 miscarriages I had: please don't do that to yourself. The worst thing you can do after loss is pressurising yourself to have another baby. It won't help you with the grief and it won't help you with TTC either. Miscarriage often deregulates your cycle for a bit, you need to have a negative pregnancy test 3 weeks after, you may not ovulate in the following cycle, you need to wait for your lining to rebuild before the next pregnancy. This is at least one full cycle in reality. Some women don't wait, but the stress of that and being unable to date next pregnancy is not a good choice. It isn't a given you're more fertile after loss either, it's a myth IMO. It's just that more women are desperate to try again quickly and they monitor their bodies and cycles better.
I tell you this because it's best you are realistic about things instead of setting up a bar that is extremely high and really painful if it doesn't work immediately.
Some of us here took a couple of cycles, some of us took few months, for some it takes longer. It will happen but give it some time, your body and mind are going through an awful lot now.
I was the same as you after my first MMC, worst thing I've ever done. Took 5 months to get pregnant again, I was driving myself mad. Then I had two more miscarriages and I'm now 22 months into attempting to become a mother with no medical issues, I've been tested through and through. Had I known that after my first loss, I'd have enjoyed life as much as I could for me and nobody else and given it time, things will come naturally and bring you peace again. Obviously my story is on the other extreme, but one thing we all had to develop after loss is resilience, in life, in TTC and in pregnancy after loss which is forever riddled with anxiety no one else can understand if they haven't been through it.
