SERIOUS QUES??? Can you poop out birth control pills...?

before they dissolve?? okay i know this is a bit gross and personal, but i need to know, so after i took my birth control pills, hours after when i use the bathroom, i noticed a small round "pill" like thing in the Kleenex, thats never happened before i started taking the pill...its happened a few times since then. is it the pill or something else? Are they not dissolving or whats going on here? is it normal?
