Miscarriage blood clots?

Isabella

I’m in the ER for my first miscarriage. I am passing clots the size of golf balls to tennis balls and it’s insanely alarming to me but everyone here is acting like it’s normal no matter how many times I tell them I’m concerned. I know they are medical professionals, but I’m just worried something else is happening. Anyone else pass clots like that? Multiple one after the other?
