brown discharge

Neva
So I started my period early but before I started I had some brown discharge. I didn't think anything about it- it's happened before but my period also last almost two days longer than normal and wasn't normal as far as flow. Now that my period has ended, I've had brown discharge for a few days. Which has never happened. It's not so much that I have to wear a pad/tampon but it's there when I wipe and there after sex. I'm not sure what to think about this. I'm 24 and I've had my period for several years now. This has NEVER happened before. Has anyone else ever had that happen? Kinda has me worried!!
