Is this the placenta? Missed miscarriage

Sy

For more details check out my previous post “ going thru a missed miscarriage right now” something like that. The pain was horrendous. And even tho I’ve been taking Advil every 4 hrs all of a sudden this excruciating pain started. I thought for sure I was going to pass out. Cold chills, light headed... I thought I had to go to the ER. but had no idea how I would make it downstairs to the door. Anyways to make my story short I sat on the toilet and began to breath and push, breath and push. I felt some clots pass then this huge clot the size of a baseball. Immediately the pain went way. It felt hard. Like hard membranes and clot consistency. Could it be the placenta? Is this ordeal finally over?
