First pregnancy, First miscarriage

Adrienne
Started bleeding Thursday evening. Went to the ER on Saturday. Ultrasound came out fine with a heartbeat but HcG levels were lower than they should've been. Didn't stop bleeding and went back today. No heartbeat and baby was only measuring at 7w 1d when I'm supposed to be 9w. 
Our hearts are broken. Not really sure how to get over this. 
D&C scheduled for tm morning.
