So today I was checking myself out. And I noticed a light yellow discharge nipple discharge. I have never had any of that before. No matter how I would "play" with my breast or nipples. My mom says I am pregnant.  (Which if I was I would be beyond happy.) but I just don't believe it. I am 5 days from my period. I took a dollar store test and it was negative, but that don't nessarily mean anything.
