What is going on?!

I really don't understand my body right now?! Last week (the week before AF) I had a small amount of pink spotting which lasted two days, then absolutely nothing for three days so I figured must be implantation, now day four I've started the same light pink spotting again so thinking must be AF arriving but it's so different to how my normal AF begins?! I tested yesterday and got a negative result, AF is was due today but so far nothing and spotting isn't progressing?! Which I could just wave a magic wand and either have my BFP or period I can't cope just hanging around overthinking every body movement!!
