D&C vs a pill? Need guidance

Me
I went in for my 10 week exam to find my baby stopped growing at 7 weeks. No heartbeat. Any chance I'll naturally miscarry or do I have to do the D&C or the pill?
I'm so confused reading various posts in this group. 
My nurse sister in law advises a D&C over the pill. 
Also how do you get explanation for why my baby didn't survive? I'm so devastated. I want to know why. 
We tried for almost 2 years for a baby and I am so sad to lose my peanut. 
I'm so scared of the process of the actual miscarriage, natural, D&C or with the pill.
