omg my boobs!!!

Ladiessss im not due for my period until the 6th but omg my boobs hurt and burn so bad as if I was breastfeeding like so much pain i could cry not only that I have had some heavy discharge and nausea i went ahead and took a lil dollar store test today and it was negative but why why why are my boobs hurting like this especially when cold i she'd some tears shit hurts lol. Could I just be gettin ready for a heavy period or what you ladies think if I was pregnant and having symptoms shouldn't a test show positive?? I had unprotected sex on the 9th 10th and 11th and once last month as well.
