Finding these in my poop every time i go, whats happening?

What are these? No, i am not taking any pills this size. Can anyone please help me identify why am i pooping hard objects. I am on a cleanse and i was given capsules filled with herbs to take.
These objects are not super solid or hard as a rock. Some of these break in half or in three parts They do have a pill shape form, they are not hollow.
