2 days after AF is due, and still no period.

I have brought so many tests and it's still negitive. How long until AF was due till your tests came up BFP?
I am extremely tired today like no other day.. I have cramps like I'm getting my period, my whole body was aching today, more my legs? Is that normal?
I still have like white discharge down there ( sorry for tmi ) I'm just all new to this and want to know your experiences! Thank you!
