TMI - What in the world just came out of me?!

No but seriously...what in the world is this?! I dropped it like it was hot about 30 minutes ago. The clot from hell?
UPDATE: Well, the evil twin to the first one has reared his head...see below,
FINAL UPDATE: I did end up going to the hospital and it was in fact a miscarriage. I am set to have a D&C tomorrow morning to finish the process my body started. Thank you all for your input!
