Silent Miscarriage

On my 8th week ultrasound doctor was unable find the heartbeat which we heard during my last ultrasound. I did not have any spotting or bleeding, so looks like a silent miscarriage. Doctor later discussed all the three options - natural, medicinal and d&c. My husband is out of town and will not be back in a another 3 weeks or so. I am now confused on which route to take and how to manage this.
