I always get my period on time give or take a few days and its always a light flow. I'm 21 and for the first time I think I have spotting but its brown like it would be after you get your period. I'm supposed to get my period in 2 days time but I have that brown flow and its not heavy but I need to use a pad still. Oh and I'm not sexually active so I don't understand this.

Maybe its an infection
