I'm sorry to hear of your m/c.

I doubt you'll get much relief before you pass the sac. I had the worst of my m/s in the week before my d&c (mm/c) and it wasn't until 24 hours after the d&c that it eased. I was told by my OB that it's the sac that prompts your body to produce the pg hormones and that it was the reason my m/s was still so bad.
