15 weeks... baby stopped at 13 weeks

I'm just wondering if anyone's had to go through this. Today at my monthly appointment it was determined that the baby no longer had a heartbeat and only measured at 13 weeks. I was told that a d&c really wasn't an option at this point. I am now waiting to deliver my baby. Has anyone had to go through this before? And if you have how did you get through it?
