WARNING! Graphic Picture. Miscarriage?

My husband and I had intercourse on the 5th when ovulating. Yesterday I had what I thought was implantation bleeding, I only bled for a few hours and I no longer am. BUT after going to the bathroom and wiping this is what I see on the toilet paper. Does anyone know what it is?!? I don't know if I am super paranoid and thinking this is a miscarriage at 5 days? 
What was inside.
