a prolapsed or external hemmrhoid?

Im 22 and am pretty sure i have a prolapsed or external hemmrhoid. About 2 weeks ago i had been constipated and had blood on the tissue when i would wipe so i took a stool softener and bought a fiber supplement which i began drinking everyday. I started to have Bm's everyday or every otherday and the blood slowly declined to where i have seen none in a good week to week in a half nor have i been constipated or had to strain. Then when i got off of work yesterday i took a nap and when i woke up it felt like something was sitting at the entrance of my anus, so i went to the bathroom and looked at it, its like a pink ball maybe the size of a pea or smaller. I had another bm today, it didnt hurt nor did i bleed, what should i do about this?? Its not really painful but i read somewhere i should try to push it back in if its prolapsed?? Will it go away on its own im kinda scared to do anything to it but i dont want it to get worse either...

Sorry for the long post...
