Miscarriage?

So this isn’t the first time I’ve had a small clump of tissue show up on my pad (this is the 3rd or 4th time I’ve had this) and I know this isn’t a blood clot… im just confused on if it’s an early miscarriage or not, and I am leaning towards a miscarriage since when I did have one most of the tissue I passed looked like this😕 I’m just lost for answers
