Does this look like miscarriage tissue? 😩

Sh

I wasn't trying to conceive in fact I started using the ring back in the beginning of july. For the last 5ish weeks now I have felt so pregnant having all the symptoms but everytime I took a test it came back negative. Then on Sunday I started heavily bleeding (like a very heavy period) with more pain than usual. Considering I was taking the ring continuously to stop periods so I thought it was weird but I thought that maybe its just because I still haven't been on the ring long.

But over the last few days the pain/bleeding has gotten worse. Then this morning as I was standing in the kitchen I felt a massive "contraction" and felt myself pass this. (This is only half of what there actually was the other half fell into the toilet while wiping).

Ive never passed anything. This large before and have obviously made an emergency appt. With my doctor for in a couple hours.

But can anyone possibly tell me if this looks like normal miscarriage tissue or if it could just be from a super heavy period?
