I did a quick Google search, and I’m guessing miso is the ulcer treatment misoprostol that you shouldn’t take during pregnancy. A d and c is a dilation and cutterage, an invasive surgical procedure that removes something from the uterus. In this instance the something was a nonviable pregnancy that went awry from possibly the medication (or other factors).

Admittedly i was also confused about miso, and immediately thought soup? I was extremely incorrect
