Missed miscarriage advice needed

Melissa
2 weeks ago, it was discovered during a sonogram that the baby no longer had a heartbeat and I was going to have a miscarriage. At that point, I was still only measuring at 6 weeks and should have been close to 9 weeks pregnant. The next day, my doctor said that she believed that my bleeding would be done by two weeks. Well, here we are and I still have not started. I had some very light spotting but nothing more. My hgc levels are dropping but are still in the thousands. My questions to the group: Is there anything doing to help the process of miscarrying "naturally" ? If anyone else has had missed miscarriage, how long did you wait before had a d&c (if you had a d&c)? My doctor wants me to miscarrying naturally and is monitoring my hgc levels until it is complete. However, I am thinking on insisting on a d&c. Any advice would be appreciated. This is my first pregnancy and miscarriage,so I am not even sure what I should be expecting or asking a medical professional. Even as I try to start to heal emotionally, I just feel a dread over me because I still have the baby inside of me. It is very wearing on an already emotional time. In addition to the emotional toll, I feel like a crampy bloated mess. Also, I am scheduled to travel out of state for work next week. It is something that could not be rescheduled. My husband is taking a couple days off work to come with me but I am just paranoid it will start bleeding when I am traveling.
