What Causes Vaginal Bleeding After A Multifetal Pregnancy Reduction Procedure?

I had fetal reduction from triplets to singleton almost a month ago. It went well, the ultrasound a week later showed the healthy baby was still alive and growing. I don t have an appointment for ultrasound for the anatomy scan for a couple days, and I have contacted the hospital that gave me my reduction and left a message.. but I am experiencing some blood loss. Most of it seems to be old blood, coming out brown... mostly when I m active... Usually only a little bit.. but when I stand for too long I end up losing what looks like mucous and sometimes red blood when I have bowel movements. Is this normal. The last 2 days I ve lost clots roughly the size of a quarter. Only 2 so far that I ve noticed... Is that probably just the identical pair bleeding out finally ? I m not experiencing pain, so I m not sure if it s a miscarriage
