Home Test...

Heidi • 30 yrs old, 2 yrs Married to an amazing fighter!
So I'm the queen of negative results 
I'm late (4 days now) and I made this test in the middle of the day (not the first wee lol) and I got this faint lightest line ever..! For some reason it made me very happy. I know I have to repeat it again I'm going to after few days but... Can this be a positive result?
Also I'm having water and white cotton discharge (sorry) most of the time now I keep thinking it might be period but when I check nada!
