Was it a miscarriage or something else?

Patient: Hi. I just went to the restroom and when I wiped down there, there. Was a bright orange (with some red and quite a bit of yellow) film-like substance with a grey lump inside if it. It reminded me of pictures of early miscarriages, I took a pregnancy test recently and was not pregnant, I even had a full period. What does this mean? I didn’t have any other miscarriage symptoms. Thank you.
