How long did it take you to start bleeding after MMC?

I found out on Monday that I had a missed miscarriage. I went in for an ultrasound at 10+6, but was only measuring 8+2 with no heartbeat. This is my second MMC in a row. With my last, I started spotting dark brown within a couple hours after the ultrasound and miscarried 3 days later. This time it has been 5 days since my ultrasound and really nothing. I started seeing VERY LIGHT brown in my CM on and off yesterday morning but that is it. I do have the medicine waiting for me at the pharmacy to induce the miscarriage, but I am having a hard time making myself do it and finding the “right time.” How long did it take you to really start bleeding after a diagnosed MMC?
