What Is The Black Tissue Like Substance Discharge From My Vagina?

Had sex 2 weeks ago and the condomn got stuck inside my vagina. My boyfriend was able to pull it out , it was pretty lodged up there. Anyway my period started about a week later and toward the end I used rephresh gel. 8 Days later I am having black filament like things coming out of my vagina. Could this be some of the condomn? No foul smell just thick white discharge small amount with the filaments.
