Brown Period?

TMI
So my period blood is brown, and it is very rarely red unless I take painkillers, then of which it is very red and heavy. 
My period is also very light, as I only go through one Barely There panty liner per day. 
Is something wrong?
Also, the white vaginal discharge before and after my periods are very heavy, sometimes to the point that I think I'm getting my period. It is heavier than my period itself.
Ps. I'm not sexually active, if that helps 
Thanks for the help!!
