Why does my period blood look like poop?

Usually after I change my pad, the blood is red. Sometimes there’s a little brown but it’s mostly red. This time, after being a week late, it came out brown! After I wiped, then it came out an orangy-red. There are so few clots. I’ve seen like 3 clots. What is this?
