Alright, help.

I'm 3 days from starting my period. My breasts for the last few days have felt engorged. Like OMG. Burning bad. I usually only cramp for days before my period shows up. Anyways.... I decided to take a test even though it's early I swear there is the faintest line. But I took the picture at 5 min and it's so faint I'm wondering if it's an evap or something because I can't tell if it even has color. So any advice would be appreciated.
