Help please idk what this means

So I had a pregnancy scare recently, I was showing all the same symptoms that I had last time I found out I was pregnant. 2 days ago I got what I think is my period but now I’m not so sure, it was 4 days early (it’s never early) and a darker thicker consistency. I never get clots when I’m on my period but this time I’m getting a lot and one of them to me is looking a little suspicious. I took out my nova ring and this came out. And it’s floating not sinking. Can this be what I think it is or am I just crazy.
