Miscarried? Pregnant? Just a weird period?

I’ve had an extremely long and run on period, ladies. It was probably one of the most annoying ones I have had. I am on the mini pill, but have been on it for quite a while now, but have never experienced this before. My period was a tad late, but when it started it lasted like 10 days, my bleeding was very strange. My first day was light brown spotting, then the next day it was more pink, and then for the rest of those days it was on and off, one day I would get hardly any blood that was brown and then the next day I would get more red blood, but not heavy at all, and it would just switch back and forth, I kept thinking it was over, but it wasn’t. And so finally it stopped. My hubby wanted to have sex today, so we did afterwards we discovered more of a liquid brown discharge which is pretty normal usually for me if we have sex close to the end of my period because it’s still clearing out a bit, but I went to the bathroom afterwards and had a brown clot that had some grey in it, I’m nervous about pregnancy, but I also feel I may have miscarried, I have miscarried before but that blood was always quite red. Don’t worry about my feeling or anything’s like that, I’m just curious at this point whether I should test, or if it’s normal, if I had a miscarriage. I’m not sure. Has anyone experienced this? Have any wisdom for me?
