Spotting

I am on cycle day 22 and I've been fine all day at work, all of a sudden I got to the bathroom to pee Nd wipe it's a pink discharge. Don't really want to get my hopes up for implantation but I'm really hoping it is. AF is due to come in 3 days(I'm praying it's not just coming early). A few days back I had a watery discharge that felt like peeing on myself lol. Does this sound familiar to anyone? Does it sound like implantation or early signs of AF?
