*Trigger* Early miscarriage - what came out of me?

So I am unfortunately going through an early miscarriage at about 5 weeks.

My lines kept getting more faint until yesterday it said “not pregnant”

I spotted yesterday around that time, and then nothing. Today I didn’t bleed or spot until about 3:00 when I noticed a little bit of brown blood.

Now I’m having pretty bad cramps. I thought I was bleeding, so I went in the bathroom to wipe and check and when I wiped, I wiped this like.. grey thing out. It looked like a ball. Like a little, grey ball. Idk how to describe it. It had the texture of thick CM, but was grey and solid and about the size of a marble.

I wish I would have taken a picture.. but I freaked out thinking that it was the pregnancy and I didn’t want to see it because I feel like it would just hurt me more.

Does anybody have any ideas on what that was?
