TMI what has come out of me?! Picture attached warning

[Slimeything]

This came out of my vagina, well truth be told I had to pull it out. What is it? It’s about 4 inches long. I’m 7 weeks post birth if that makes a difference. Anyone with any experience?

Might it be a decidual cast?

Looks like thick discharge? If not part of your sack maybe?

Looks like a tapeworm

Tapeworm comes from your butt though

Definitely not a tapeworm.
Was thinking extreme EWCM? Or infection maybe? But there isn’t any smell.

Super worried about getting pregnant again and didn’t want it to be some symptom of that happening.

Isn't that just the stringy ovulation stuff? Maybe you've ovulated again
