Colposcopy

So I just had a colposcopy with biopsy 2 days ago for my hpv and the doctor said it's very mild and she highly doubts there's anything else but still took a biopsy just to make sure there's nothing. She told me I might have some cramping and perhaps discharge with color being brown after she finished, & I'm suppose to get my period next week. I have noticed the cramping here and there and the light discharge of the brown when I wipe but I just went to the restroom and a pretty big clot came out it wasn't a blood clot like when I have my period it was like if it was a dirty old wet cotton ball I kind of freaked out because it was thick enough for me to feel it come out I wasn't sure if this was normal because of the biopsy or not. Anyone have the same experience?
