Having 5 days of brown discharge. Pregnancy sign??

Kristen
So I'm on CD 32 and have had brown spotting for the past 5 days.  I took a test Friday cuz I'm a POAS addict, even though I figured it was the start of my period. 
Well period has not started and I decided to take a look at that test again and now I see a faint line. So so faint. I had to take the FRER apart to get a photo even. 
Thoughts?! I'm testing tomorrow. I would have today but I really thought the blood blow was going to start
