Neg or Preg !? I just don't know

I can't count how many days I'm late! But I'm use to being late due to my Polycystic Ovarian Syndrome (PCOS) . My biggest issue now is cramping. I cramp all day for the past 2 days. I've wiped TO what I thought would be a period , but all I've seen it's a couple of pink spots on my tissue . Implantation bleeding is brown right? And oh God! The torture of my nipples feeling like there are being pinched all day is driving me nuts!! It's so bad I want to set my TaTa's free during work ! Yesterday I took a test and it's negative . What should I do ? I'm so confused ! (Btw , the last time I had intercourse was 9/21 and 10/4 )
