I think this came out of my vagina? Tmi Warning sorta

This clearish glob/snot substance.. it's pretty firm idk?jelly like? Anyone have any idea? I don't have any std or sti btw. But idk I'm still worried. This has never happened to me before. Very thick consistency. Sexually active, only one partner. Ttc. If that helps 
Sorry it doesn't give me the option to put TMI OVER THE PICS.🙄🙄😫
