TMI PHOTO!

Sorry if this is too much, but I went to the ER yesterday for heavy bleeding, clotting, and cramping. They did an ultrasound and saw the baby with a heart rate of 80 and I was measuring at 6 weeks, exactly where I should be. Doctor said there was a good chance I would miscarry due to bleeding. This morning I passed this. I examined it but I had no idea what I was looking at. Did I pass the baby or does anyone know what this is?
