Waiting for natural miscarriage

This is my second loss. My first was in 2015, and the baby stopped growing at 6 weeks. I had my daughter in Dec 2016 and we were so excited for baby 2. I had an ultrasound Wednesday and the tech couldn’t find a hearbeat and the baby was only measuring 6w2d. I should have been 9 1/2 weeks.

I have had some bleeding and cramping, but nothing like the first time. My first miscarriage started on a Thursday afternoon and was over the following night. My bleeding started Thursday and has continued with varying intensities. I feel like it should be progressing more. I plan to call my midwife tomorrow.

Did anyone else experience a similar situation?
