TMI - placenta?

So on Wednesday I was confirmed to be having a miscarriage, and Thursday night I started passing everything. There were large clumps and I am fairly positive I passed the baby, right around 4:30am yesterday. Last night around 11:30 after hours of pain I finally passed what seems to be the last of the clots. I believe it’s the placenta but was just wondering if anybody has been through this and can say whether or not it might be?

My friend put her hand as a size reference lol.
