You may not get conclusive results. With my mmc, bub had passed 2 weeks earlier so there werent any live cells they could cultivate to karotype. I hope you get some answers but I've found most of the time it's "one of those things".

Different women bleed differently after a d&c. Mine was quite light. The first period after can be heavy though. I didnt get milk with my early losses but did with DS2 (with DS1 I took the pill). I found homeopathic drops helped for the pain and engorgement.

I found between the grief and the hormonal changes, that I was a mess for weeks. Just when I thought I was getting better I'd have another meltdown. I wrote bub a letter, gave bub a name and had a goodbye ritual at the ocean, which helped me.

As for what to do next: grieve. Be gentle with yourself. Now is not the time to make decisions. Take some time and when you're feeling stronger, you can look at your options then.
