Options for missed miscarriage

After two ultrasounds that showed no heartbeat and about two weeks behind in growth (no change in growth over 6 days), I know that I will miscarry but I'm in a waiting game. I'm 9 weeks with a fetus that measures 6 weeks, 4 days. The emotional side is of course terrible, and I'm having no bleeding or cramping, but still having morning sickness. My doctor was willing to let me wait as long as 3 weeks to allow my body to naturally miscarry. I'm debating if I should take the misoprostal to speed up the process. I could get it from my doctor at any point. My doctor doesn't recommend D&C until you've tried misoprostal. I'm kinda stuck and would love thoughts from those who've done it. Part of me wants it over with, part of me can't stomach taking a medicine that will officially end the pregnancy. My mom wants me to get a second opinion at 10 weeks but I'm not sure it's necessary. Any help?
