Miscarry

Hi ladies, I went in for my first ultrasound a week ago, and they couldn’t find baby’s heartbeat, I asked for another ultrasound in a week and they agreed, well there was still nothing. The baby was measuring at 11 weeks, and I still haven’t started the miscarriage process, no bleeding, no anything. I want to give my body some time to let it happen naturally, if it doesn’t, I will do whatever necessary. I was just wondering to anyone that went through something similar, when did you finally start to cramp and bleed? How long did it take you?

Thank you in advance!
