Brownish discharge...

So I had 3 day period (My periods usually are 4-5 days..) it was normal like a normal flow. 2 days after I had brown/Red discharge was not watery really and then 2 days after that I had more brownish discharge is was more liquid like. I've heard that it could just be the body cleaning up after my period but then it happened again 2 days later... not sure if this is normal?
