** TMI ** Heavy Brown- Black Discharge with Clots

My period is supposed to come in 4 days today I wiped and it was brown. I was confused, it wasn’t that heavy so I didn’t think much of it. When I went again it was much heavier and filled with black clots, (in the picture) it continued to be a little bit less heavy but still flowing off and on with clots. I tried looking it up and it could be the beginning of my period and old blood shedding from my last period but my last period was 10 days long last time and I dont see why it would still have anything to shed 😂 . Im not sure though.
