VERY TMI WARNING!! ⚠️⚠️

I am currently on day 6 of my period today. Yesterday while I went to the bathroom I tried to go poop but I couldn’t and when I went to while I saw this.

What kind of discharge is this. I’ve never had this before. Does this mean something with my uterus? Or is this normal maybe? Or is it something with fertility? Help please!!!
