What was your interpretation of miscarriage before you had one?

I feel like I never understood miscarriage before I had one, and I feel like that was pretty normal. I viewed miss carriage a seeing a clump of blood, which was really be the baby, And some bleeding obviously. When in reality it was the two most horrific things I have ever seen and have to go through. I honestly almost died the first time it happened. And the process took 9+ hours both times and numerous trips to the ER. I would just love to know what everybody else’s experiences are with that and if it seems to be “normal”or not?
