The process is starting- really nervous

It's been 4 weeks since our baby passed away and I chose to miscarry natural. I started bleeding right before getting on a plane to fly home and now are driving me to lead worship at a youth retreat. My cramps are increasing coming in waves with a dull pain that lingers...  Nervous to finally experience what I have been anticipating since we found out our baby passed. Any advice or encouragement to hold on to... It's such a lonely feeling.
