am I pregnant?

Okay I'm due for AF 6/26 (in 6 days) I spotted once 2 days ago I was just wiping and had tiny bit of blood my boobs where killing me for the last 5 days but kinda settled down. I have not been able to sleep at night i stay up until at least 2am every night this past 6 days and sleep all day long. I have been feeling sick and dizzy on and off all day. I took a test and got a BFN I'm so sad:( but test said it could tell 6 days early but that mean 5 days before expected AF and I am at 6. I just want to start our family. Someone help me. How can I feel all of these things and not be pregant??? Today I started getting weird cramps almost felt like a side ach. I have been having light cramps for a few days but not like this. I'm also super moody. Ugh someone help me.
