Help, please!!!

For the past 6 days I've been having this Brown discharge. It's very light, and I don't need to wear a pad or a panty liner. It only comes out when I urinate. The first three of the 6 days I didn't cramp but now I'm cramping. It's not a period it's way too light and it started a week before my period. It's scary and I don't know what to do. Should I go to the hospital? I have no idea what's going on.
